BACKGROUND OF THE INVENTION

The skin (epidermis) of humans (and of terrestrial vertebrates) may suffer from a number of problems, such as: acne; wrinkles, including age spots; infections; physical damage; various rashes, including pityriasis rosea, acne rosacea; and the like. Each of these skin problems may be briefly discussed below.

Acne may result from clogged skin pores, which may be visible as pustules or pimples—i.e., what are commonly called blackheads and whiteheads. Such visible acne may be both visually unpleasant and painful. Severe acne may also result in scaring from the physical damage associated with ruptures of follicle walls, which may also form deep cysts under the skin. The clogged skin pores visible as acne may result from an overproduction of sebum oil, keratin, and/or metabolic byproducts of skin pore bacteria, as well as from the cells of skin pore bacteria. A common skin pore bacterium is Propionibacterium acnes (P. acne).

Undesirable wrinkles on the skin may result from age, environmental factors, genetic factors, and repeated facial expressions. Age may be a factor in wrinkle formation because as skin ages, it may lose elasticity, in part due to accumulated gravitational pull over time and changes in connective tissues. Additionally with age, sebum production may slow (from the sebaceous glands), which may contribute to skin dryness with age, wherein such skin dryness may enhance visibility of wrinkles. Environmental factors may include sun and wind exposure as well as exposure to smoke, which over time may also contribute to wrinkles. Further, consistent facial expressions over time such as squinting, smiling, and even thinking can result in skin wrinkles. And in addition to wrinkles, age spots, such as liver spots and solar lentigines may also appear on the skin as the skin ages and is exposed to various environmental factors over time.

Additionally, various microorganisms, which may include bacteria, fungi, protozoans, and even some small invertebrates may infect skin, both on the surface and within the skin tissue, with varying levels of severity. For example, the mere presence of some such microorganisms, whether dead or alive, may act as an irritant, causing inflammation. Some microorganism metabolic byproducts may also act as irritants; whereas, some byproducts may actually be toxic. And some microorganisms may actually feed on the skin itself and/or the natural secretions of the skin, such as sebum. Such microorganisms may also infect open wounds on the skin and use such open wounds to gain entry to the body, and pose a larger bodily infectious threat.

Additionally, viruses may cause contagious, painful, and/or unpleasant looking lesions and blisters, e.g., cold sores. Such lesions and blisters if ruptured may result in physical damage to the skin, as well as pain. Such viruses may include herpes and herpes like viruses.

With respect to physical damage to the skin, this may include: various wounds, cuts, abrasions, burns, lesions, blisters, ruptures, and the like. Such physical damage to the skin may result in scarring as the skin heals and prior to healing may increase chances for various microorganism infection.

Such skin problems, particularly when occurring on the face, because of the inherent visibility to others of the face, may result in collateral detrimental effects, such as to one's psychological, social, and occupational wellbeing.

Pityriasis rosea may be a type of skin rash. Often, pityriasis rosea may begin with a single “herald patch” an oval red lesion of 2 to 10 centimeters (cm), followed in one or two weeks by a generalized body rash of many small (5 to 10 millimeter (mm)) patches of pink and/or red, flaky, oval shaped lesions, which often appear on the torso, but may also appear on the cheeks and/or at the hairline.

Acne rosacea or just rosacea may be a chronic skin rash condition characterized by facial erythema (redness) and sometimes pimples. Rosacea may affect all ages. Rosacea may typically begin as redness on the central face across the cheeks, nose, or forehead, but may also affect the neck, chest, ears, and/or scalp. In some cases, additional signs, such as semi-permanent redness, telangiectasia (dilation of superficial blood vessels on the face), red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma), may be present.

The prior state of the art has responded to such problems with a diversity of technologies. For example, there may be a plethora of various topical ointments and creams for treating various skin problems. However, relevant here, may be the application of soaking the affected skin in an immersion liquid. Regardless of explanation, the prior state of art has shown a positive correlation with improvements to the above noted skin problems with soaking the skin in an appropriate immersion liquid. For example, such a treatment modality may be known in the art generally as hydrotherapy when the immersion liquid in question may be predominantly water. However, such hydrotherapy principles may be applied to other such immersion liquids, such as various oils, various paraffin waxes (typically heated), and oil water mixtures (emulsions). As used herein, hydrotherapy may be a means of treating various skin problems, by immersing the skin in a particular immersion liquid, wherein the immersion liquid may be predominantly water or some other liquid, such as an oil in liquid form at room temperature or an appropriate temperature, such as paraffin wax in liquid form when appropriately heated, or an oil and water mixture.

Such hydrotherapy may involve soaking a target region of skin within the immersion liquid. The immersion liquid may comprise various properties. For example, the immersion liquid may contain various dissolved salts, wherein such a liquid may be known herein as a saline solution. For example, the immersion liquid may contain released oxygen, either as dissolved oxygen and/or as gas bubbles within the immersion liquid. For example, the immersion liquid may contain an increased or decreased temperature with respect to room temperature. And for example, the immersion liquid may be directed via one or more jets, such that a stream of liquid pressure may be directed at the target region of skin.

With respect to saline solutions as the immersion liquid, saline and salts as used herein may refer not only to solutions of sodium chloride, but may also refer to other minerals in solution, e.g. potassium and/or magnesium, that may be dissolved in a solvent, such as predominantly water. Various negative ions, such as chloride, may also be present in solution with the positive mineral ions. For example, sodium and potassium salt solutions may be present with chloride ions and magnesium may be present with sulfate ions, as in Epsom salt. An immersion liquid using various salts may promote different benefits. For example, some such saline solutions may soften the skin and/or others may tend to moisturize the soaked skin.

Benefits to the skin from soaking the skin in saline solutions may predominantly function by osmosis. Osmosis is a random movement of water molecules across partially-permeable membranes (such as cellular membranes, including skin cells), from an area of high water concentration (e.g. within a cell) to an area of low water concentration (e.g. the saline solution). Thus osmosis will function to draw water out of cells, including skin cells, when the saline solution has a salinity that is greater than the salinity within the cells. For example, human blood has an average salinity of about 0.85% by weight, which is often rounded to 0.9%. Thus if the saline solution that the skin may be soaking in is greater than 0.9% by weight, there will be osmotic flow of water molecules from the skin cells into the saline solution.

However, it is from this flow of water molecules across cell membranes that several benefits may result for treating and/or improving the various skin problems noted above.

For example, with respect to acne, skin with acne that is exposed to saline solutions may see a reduction in acne. Such reduction may result from the saline solution reducing sebum oil within pores, by the saline solution reducing the population of skin pore bacteria, and/or by the saline solution encouraging a reduction in skin pore size. The saline solution may help to loosen sebum oil from pores. With respect to skin pore bacteria, which may be adapted for non-saline environments, such bacteria may not be adapted to cope with the osmotic flow of water molecules out of the bacterial cells. Such saline solutions may hinder reproduction of such bacterial cells. Such saline solutions may actually kill such bacterial cells. With respect to the reduction in skin pore size, this may also result from osmotic flow of water molecules.

With respect to a reduction in wrinkles, the saline solution may reduce wrinkles by softening the wrinkled skin tissue and by stimulating the sebaceous glands to produce sebum oil which may combat age associated skin dryness. For example, exposing a face to warm water may soften facial skin in preparation and aiding in shaving whiskers (stubble) from that face. Additionally, depending upon the salinity of the given saline solution, the saline solution may have a hydrating effect upon the immersed skin.

With respect to mitigating against microorganism infection of the skin, as noted above, those microorganisms which may be predominantly present on the skin are not typically adapted to withstand osmotic flow of water molecules from within the bacterial cells. Immersion of skin in such saline solutions may result in microorganism population reduction.

With respect to improving a rate of healing damaged skin, skin immersed into saline solutions may experience an improved rate of healing by reducing the populations of microorganisms which may interfere with healing. And the osmotic flow may also aid healing damaged skin by aiding transport of nutrients and repair proteins from within the cells and tissues below the surface skin to the damaged skin site.

Thus immersion of skin into a saline solution which may have a salinity greater than the skin tissue being immersed, may result in a plurality of benefits to the immersed skin.

Now turning to oxygen treatments for the skin and how oxygen may reduce some of the skin problems identified above. Again, regardless of explanation, the state of the prior art shows a positive correlation with exposing skin to oxygen and improvements in the skin.

Molecular oxygen (atmospheric oxygen), i.e. O₂, may be essential for cellular respiration and the basis for how each vertebrate cell derives energy via the Krebs Cycle (Citric Acid Cycle). Without a sufficient supply of consistent oxygen to any vertebrate cell, that cell may be hypoxic and may have a diminished capacity to operate normal cellular activities, including a diminished capacity to reproduce, to fight infection, and/or to heal. By providing oxygen in sufficient concentration directly to the skin, such exposed skin may obtain some of its needed oxygen directly, instead of relying largely upon delivery of oxygen via hemoglobin in red blood cells. Such skin cells having a steady available source of oxygen may allow such skin cells a full range of normal cellular activities. Additionally, immune system cells (e.g. macrophages and phagocytes) which target and kill infectious microorganisms better perform when such cells have an adequate supply of oxygen. And a second mechanism of oxygen reducing infectious microorganism population may be by oxygen's oxidation properties and ability to form reactive oxygen species that may then oxidize bacterial cellular machinery, such as interfering with bacterial cell walls.

Now oxygen may be applied to the skin in gaseous form and/or released as a dissolved gas and/or as gas bubbles within a liquid, including the immersion liquid. For example, atmospheric air will contain atmospheric oxygen, e.g. at approximately 20.95%. A delivered concentration of gaseous oxygen may be increased over the atmospheric percentage by using pure oxygen as a supply source. However, use of gaseous oxygen directed at skin may have the drawback of being difficult to control and manipulate due to the gasses' inherent ability to more freely and disperse. Whereas, release of oxygen in a liquid may provide for better control as the target area of skin may be immersed in the liquid, which then may have oxygen from air or pure oxygen released into the liquid.

The benefits of oxygen and saline solutions may be combined into the same immersion liquid. For example, air (which includes oxygen) and/or oxygen may be pumped or released into an appropriate saline solution. Additionally, such an oxygenated saline solution may be combined with the benefits of controlling a temperature of the oxygenated saline solution.

For example, increasing a temperature of the immersion liquid above room temperature but less than a temperature which may be harmful (e.g. painful), allows for an increase in chemical reactions (kinetics). Thus increasing the immersion liquids temperature in such a range will tend to increase the effectiveness of saline solutions as well as the effectiveness of oxygenation of the skin. Additionally, such increased temperature of the immersion liquid may result in an environment that may be soothing and relaxing to a user. Such a soothing and relaxing result may then release stress and mitigate against headaches. Release of stress may promote lowering of blood pressure, healing of damaged skin, and a stronger immune system. Thus, increasing the temperature of the immersion liquid not only may provide direct improvements to how the saline and the oxygen functions to improve the skin, but by creating the soothing and relaxing environment, a collateral benefit of stress release may be achieved, which may also then include a cascade of additional benefits.

Further, increasing the immersion liquids temperature above room temperature may then permit the immersion liquid to be used for heat therapy. Heat therapy may be used to treat not only skin problems, but also other ailments, such as, but not limited to, arthritis, osteoarthritis, fibromyalgia, joint stiffness, bursitis, tendonitis, sprains and pulled muscles. The heat and immersion liquid which may convey the heat, may increase blood flow, improve joint stiffness and reduce pain. For example, heated paraffin waxes as the immersion liquid may be utilized. Such heated paraffin wax may soften hardened skin caused by scleroderma, a disease in which collagen accumulates on the body.

In addition or alternatively, decreasing the immersion liquids temperature below room temperature may then permit the immersion liquid to be used for cold therapy. Chilling the liquid by use of a chiller, chilling equipment, and/or by introduction of ice, may then permit various cold therapies to be used to treat the face or other body part which may be removably immersed into the chilled liquid. Additionally or alternatively, heat therapy may be alternated with cold therapy; wherein such alternation of warmth and cold may aid in increasing blood flow, facilitating removal of cellular toxins (e.g., but not limited to, lactic acid), and/or promoting healing of burned or traumatized tissue.

Additionally, liquid jets, for example water jets, when directed at the immersed skin may also result in an environment that is soothing and relaxing to the user. Such water jets also may have their benefit increased when the immersion temperature is increased as noted per above.

Light therapy may also be used to impart various benefits to the exposed skin and/or body in general. Light therapy may involve directing a source of light at skin. Some wavelengths of light have found to increase healing rates of damaged skin, such damaging including cuts, scrapes, bruising, lacerations, lesions, and the like. Light such as ultraviolet (UV) light may also be used for skin tanning purposes. However, both existing oxygen therapy and existing light therapy are conducted in a treatment environment of atmospheric air, i.e., not with an article to be treated (e.g. a region of skin) submerged within an immersion liquid.

Additionally, it may be desirable to expand beyond just oxygen, air, or air enriched with oxygen, as treatment gasses for skin.

Additionally, current light therapy devices generally are directed at emitting only a very narrow range of wavelengths, generally within the visible light spectrum, near infrared (IR), and near ultraviolet (UV). It would be desirable to have expanded devices that may be capable of emitting electromagnetic (EM) radiation in various wavelengths that may encompass regions of the entire EM spectrum, i.e. not necessarily a single device capable of emitting across the entire EM spectrum (since different technologies may be required to produce a given range of wavelengths), but rather a multitude of EM emitting devices where each different device may be capable of emitting a particular range of wavelengths, such that these different EM emitting devices may collectively be able to cover the entire EM spectrum.

Conducting oxygen therapy and/or light therapy or other EM therapy within the immersion liquid may be desirable for several reasons. Because the liquid is more dense than atmospheric air, more control over directing oxygen (or other gas) to a target region on the article (e.g., immersed skin region) may be achieved over conducting oxygen therapy in atmospheric air, where expelled oxygen quickly dissipates into the atmospheric air. By using the immersion liquid to removably submerge the target region of the article, useful properties of the liquid may be tailored for specific applications with respect to the target region of the article. For example, liquid water, such as saline solutions, may soften the skin and make such softened skin better able to benefit from exposure to oxygen and/or various wavelengths of light. The additives in the liquid may be used to heal, cleanse, rejuvenate, sanitize, sterilize, and the like. Likewise, controlling a temperature of the liquid may then be able to impart heat or withdraw heat from the target region of the article in a much greater efficiency than may be possible where the treatment environment is atmospheric air and not the liquid. Additionally, controlling the temperature (up, down, or maintaining) of the liquid may increase or decrease the efficacy of the additives, e.g., from a kinetics perspective.

Furthermore, it has been discovered that conducting light therapy or other EM therapy may be enhanced when the EM radiation may be emitted through a plurality of bubbles within the immersion liquid, by providing an increased coverage of the target region of the article receiving EM radiation in comparison to if there were no bubbles. The emitted EM radiation and the bubbles produce an optical chain reaction (OCR) phenomena that provides this enhancement.

However, as noted above, with respect to such skin problems on the face, these problems are exacerbated because the high visibility of the face. Additionally, these skin problems on the face are exacerbated because the current state of the art does not provide a means by which the user may immerse the face to receive hydrotherapy, wherein the hydrotherapy immersion liquid may comprise saline solutions, delivery of oxygen (and/or other gasses), heating means for increasing and/or decreasing immersion liquid temperature, and/or use of liquid jets. The problem that the prior state of the art has failed to address, until this invention, results from two biological facts. One, terrestrial vertebrates breathe from their nose and/or mouth located on the face and thus a hydrotherapy means for the face needs to provide a means by which the user may breathe while the user's face is immersed. Otherwise immersion of the face is limited to how long the user can hold their breath. And two, all pre-existing vessels have no means to accommodate a neck region of the user, particularly the soft tissue regions of the neck (front and sides of the neck), so if the user were to submerge the user's face into a pre-existing vessel, a rim of that vessel would press into the neck region causing discomfort rendering the prior state of the art ineffective for hydrotherapy of the face. Or the user would have to angle their head into the prior art vessel and attempt to hold their head at an uncomfortable angle to soak their face, which if is prolonged may result in neck pain. Additionally, it may be desirable if such a device might, in at least some embodiments, comfortably support the head region of the user, particularly the forehead, to promote facial immersion that may be comfortable and not strain the neck; wherein the user may soak their face, in comfort, for extended periods of time.

There is a need in the art for devices and/or methods that permit treating specifically targeted regions of the articles (e.g., skin) to be removably submerged in the immersion liquid and then treated with various gas bubbles, such as oxygen, treated with various wavelengths of EM radiation, such as visible light, and/or providing for an enhanced EM radiation coverage of the treated region by a synergistic combination of EM radiation and bubbles that may result from directing EM radiation through bubbles in the liquid.

There then is a need in the art for a device which may promote comfortable face immersion into the immersion liquid that both allows the user to breathe while the face is immersed and that may be comfortable to the neck of the user.

It is to these ends that the present invention has been developed.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of face soaking devices, article soaking devices, and flexible detachable vessel covers are described and disclosed; as well as methods of use. In some exemplary embodiments these face soaking devices may comprise a vessel with gasket-accommodator, a vessel neck gasket, and a breathing apparatus. The vessel may be configured to hold an immersion liquid (liquid) to submerge a face of a user or a portion thereof. The vessel neck gasket may be removably joined to the vessel. The vessel neck gasket may be configured to comfortably accommodate a portion of the user's neck. The breathing apparatus may be in removable contact with: the vessel, with a head rest subassembly, and/or with the user. The breathing apparatus may be configured to permit the user to breathe while the user's face may be submerged within the liquid. When the vessel may be filled with the liquid to at least a sufficient level, the user may soak the face or the portion thereof, such that skin being soaked may receive a benefit.

Note, the term, “removably” as used within this disclosure may mean the two or more components being referenced in the sentence with “removably” may be in some embodiments be removable from each other. However, such use of “removably” is not intended to eliminate embodiments wherein the two components may not be removable. For example, as used above, in “the vessel neck gasket may be removably joined to the vessel” may mean in some embodiments the vessel neck gasket may be removed from the vessel (e.g. to effect repairs or replacement of the vessel neck gasket); whereas in other embodiments, the vessel neck gasket may not be removed from the vessel.

The benefits the user may derive from such face soaking may depend upon a number of factors. Some of these factors may include, but are not limited to, how long the user submerges their face in the liquid in any given use of the face soaking device, how often the user may use the face soaking device, and/or of characteristics the liquid.

For example, and without limiting the scope of the present invention, the characteristics of the liquid may comprise: the predominant chemical species of the liquid (e.g. water, oil, paraffin wax, water oil mixture, etc.) (which may be functioning as a solvent and/or carrier); an amount of air, oxygen, and/or gas present in the liquid (whether dissolved or not); a temperature of the liquid; whether or not the liquid may be circulated; and/or whether or not the liquid may be directed at a portion of the immersed face via a jet nozzle (or some other forced movement means). In some embodiments, the predominant chemical species may also comprise further additives, to provide various treatments. In some embodiments, these further additives to the liquid may comprise one or more of: salts, mineral salts, organic salts, minerals, active pharmaceutical ingredients, dyes, oxidizers, bleaching agents, lightening agents, cleansers, sanitizers, spices, fragrances, essential oils (e.g., in the context of the cosmetics industry), herbs, homeopathic ingredients, and/or medicinal ingredients. For example, and without limiting the scope of the present invention, such herbs may include herbs found in one or more of traditional Chinese medicine, traditional Japanese medicine, traditional Indian medicine, traditional Native American medicine, and the like. For example, and without limiting the scope of the present invention, such herbs may include various teas, including herbal teas and/or teas from the tea plant (tree). Some of these characteristics of the liquid may be inherent with the liquid and/or some of these characteristics of the liquid may be imparted to the liquid from the face soaking device.

For example, and without limiting the scope of the present invention, some such inherent properties may be chemical properties derived from the chemical composition of the liquid. In some embodiments, the liquid may be a saline solution, derived from dissolving various salts within water, oil, and/or an oil and water mixture. Such salts may comprise various positive ionic minerals with complimentary negative ions. Such minerals may include sodium, potassium, magnesium, and the like. Such negative ions may include chloride, sulfate, and the like. For example, such salts may be sodium chloride, potassium chloride, magnesium sulfate (Epsom salt), and the like. Different positive mineral ions may provide different benefits to the skin being soaked within the face soaking device. For example, some such positive mineral ions may tend to soften the skin, while others may tend to moisturize the skin. For example, Epsom salt baths tend to both soften and moisturize immersed skin.

Note, the term “saline,” and/or “saline solution” may often be used to denote a salt solution comprising sodium chloride dissolved in water. Within this disclosure, the terms “saline” and/or “saline solution” may refer to any salt solutions, such as sodium chloride, potassium chloride, magnesium sulfate, and the like.

Such chemical properties, such as osmotic pressure, may be a function of salt concentration. In some embodiments, where it may be desirable for there to be an osmotic flow from within the immersed skin tissue towards the liquid, the liquid should have a salt concentration greater than 0.9% by weight.

In some embodiments, the liquid may be provided by the user. In such embodiments, the user may be free to formulate the liquid in any number of different ways. For example, the user may determine which salts to employ, or a mixture of salts. The user may set the salt concentration. The user may also add other additives and/or ingredients for other desired effects. For example, the user may use their own home-remedy recipes that may rely upon various herbal, mineral, homeopathic, and/or medicinal ingredients. Additionally, various licensed medical practitioners, may provide prescriptions for various formulations of liquid to be used within the face soaking device.

In some embodiments, a supplier of a face soaking device may provide various packets to be mixed with water, oils, paraffin waxes, and/or oil and water mixtures to formulate a given desired liquid for use within the face soaking device. These packets may comprise the various additives as noted above.

In some embodiments, the supplier of a face soaking device may provide recipes so that the user may mix and formulate the given desired liquid for use within the face soaking device.

For example, and without limiting the scope of the present invention, some such imparted characteristics of the liquid may be the amount of air, oxygen, and/or gas present in the liquid (whether dissolved or otherwise); the temperature of the liquid, whether or not the liquid may be circulated; and/or whether or not the liquid may be directed at a portion of the immersed face via the jet nozzle.

For example, and without limiting the scope of the present invention, the temperature of the liquid may be controlled with various heaters, chillers, and/or with ice. Chilling the liquid by use of the chiller, chilling equipment, and/or by introduction of ice, may then permit various cold therapy to be used to treat the face or other body part which may be removably immersed into the chilled liquid. In some embodiments, the liquid may be substantially ice. Additionally or alternatively, warm (or hot) therapy may be alternated with cold therapy; wherein such alternation of warmth and cold may aid in increasing blood flow, facilitating removal of cellular toxins (e.g., but not limited to, lactic acid), and/or promoting healing of burned or traumatized tissue.

Additionally, such face soaking devices may also be used for other purposes. For example and without limiting the scope of the present invention, face soaking devices may also be used: to relax, to facilitate face washing, to facilitate face soaking in preparation of facial shaving, as a wash for eyes, as a means to soak hands and/or feet, lower arms, lower legs, and the like.

In some uses, such face soaking devices may be used to lighten skin shading of the user, for example, by adding one or more oxidizers or bleaching agents to the liquid. For example, and without limiting the scope of the present invention, various concentrations of hydrogen peroxide may be used in the liquid as an oxidizer. In some uses, such face soaking devices may be used to lighten skin shading of the user, for example, by adding one or more lightening agents which may disrupt melanin production to the liquid. For example, and without limiting the scope of the present invention, various concentrations of hydroquinone may be used as a skin lightening agent. In some embodiments, one or more other skin lightening agent may be used with various embodiments of face soaking devices, such as, but not limited to, deoxyarbutin, glycolic acid, kojic acid, corticosteroids, niacinamide, retinol, soy, licorice extract, arbutin, and the like.

Conversely, in some uses, such face soaking devices may be used to darken skin shading of the user, for example, by imparting ultraviolet energy to the liquid to then tan the exposed skin. For example, and without limiting the scope of the present invention, ultraviolet light sources may be directed to impart ultraviolet electromagnetic (EM) energy into the liquid with sufficient intensity to provide an effect upon the user's skin. Or alternatively (or in addition) to ultraviolet treatment, one or more dyes (permanent or temporary) may be added to the liquid to change the hue (shade) of the user's skin. For example, and without limiting the scope of the present invention, one or more of dihydroxyacetone (DHA), erythrulose, melatonin (including derivatives and synthetic derivatives such as Melatonin II), and the like may be added to the liquid to darken (tan) the skin.

That is, various embodiments of face soaking devices may be used to lighten and/or darken hues, tones, and/or shades of skin.

In the following discussion that addresses a number of embodiments and applications of the present invention, reference is made to the accompanying drawings that form a part thereof, where depictions are made, by way of illustration, of specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and changes may be made without departing from the scope of the invention.

FIG. 1A may depict an exemplary embodiment of an overall assembled face soaking device 100, shown from a top perspective view, wherein at least a portion of a face 9010 of a user 9000 may be substantially immersed in a liquid 101 (see FIG. 1B); that may be removably contained within a vessel 200 of face soaking device 100. FIG. 1B may depict a longitudinal cross-section of face soaking device 100 of FIG. 1A, wherein the at least the portion of face 9010 of user 9000 may be substantially immersed in liquid 101 removably contained within vessel 200 of face soaking device 100.

In some exemplary embodiments, as may be depicted in FIG. 1A and FIG. 1B, face soaking device 100 may comprise: vessel 200, a vessel neck gasket 340, and a breathing apparatus 400.

Continuing discussing FIG. 1A and FIG. 1B, in some embodiments, vessel 200 may be configured to hold liquid 101 in a sufficient volume to submerge a whole face 9010 of user 9000 or a portion thereof. It is obvious to one of ordinary skill in the art, that vessel 200 may be configured to hold liquid 101 at a sufficient level to permit user 9000 to submerge (immerse) the whole of face 9010, or a portion thereof within liquid 101, while liquid 101 may be held within vessel 200. This sufficient level may be a liquid level where when user 9000 inserts face 9010 into internal volume 220 and rests a first portion of neck 9020 upon vessel neck gasket 340, such that face 9010 may be completely immersed in the liquid. The maximum liquid level of vessel 200 may be greater (higher) than this sufficient level.

In some embodiments, vessel 200 may comprise at least one wall 201 and at least one base 215. At least one wall 201 and at least one base 215 may be in physical contact with each other. (See e.g., FIG. 2AG for at least one base 215.) At least one wall 201 may comprise a neck-gasket-accommodator 335. (See e.g., FIG. 3G for neck-gasket-accommodator 335.) Neck-gasket-accommodator 335 may be configured to accommodate vessel neck gasket 340. In some embodiments, neck-gasket-accommodator 335 may be formed as a cutout into a region of at least one wall 201, from a top of vessel 200. In some embodiments, neck-gasket-accommodator 335 may be formed as an integral molded structure of a region of at least one wall 201. Vessel neck gasket 340 may be removably joined to vessel 200. Where vessel neck gasket 340 may join vessel 200, i.e., along such surfaces of physical contact, a primary water tight seal may be formed in or at the vicinity of neck-gasket-accommodator 335. For example, and without limiting the scope of the present invention, in some embodiments, this vicinity of neck-gasket-accommodator 335 may be two inches or less. In other embodiments, other distances may be used for “the vicinity of neck-gasket-accommodator 335.” Vessel neck gasket 340 may be configured to receive a first portion of a neck 9020 region of user 9000 when the whole face 9010 or the first portion thereof may be submerged in liquid 101. The first portion of the neck 9020 region of user 9000 may be where neck 9020 physically contacts vessel neck gasket 340. Note, the nature of the physical contact between the first portion of the neck 9020 region of user 9000 and vessel neck gasket 340 may be removable. When vessel neck gasket 340 may receive the first portion of the neck 9020 region, a secondary water tight seal may be formed between this first portion of the neck 9020 region and vessel neck gasket 340. Note, vessel 200 may be further detailed in the FIG. 2 series of figures and discussed below in the FIG. 2 series of figures discussion. Note, vessel neck gasket 340 and neck-gasket-accommodator 335 may be further detailed in the FIG. 3 series of figures and discussed below in the FIG. 3 series of figures discussion. (Note, this paragraph may in general refer to FIG. 1A and FIG. 1B, but with some of the references to structures and/or components being discussed in greater details below.)

In some embodiments, breathing apparatus 400 may be in physical contact with vessel 200, as may be shown in FIG. 1A and FIG. 1B (and focused on in the FIG. 4 series of figures). In some embodiments, a breathing apparatus embodiment may be in physical contact with a head rest subassembly 2100 (see e.g. FIG. 21 series of figures). In both embodiments, the nature of the physical contact between breathing apparatus embodiments (e.g., 400) and vessel 200; or between breathing embodiments and a head rest subassembly (e.g., 2100), may be removable in some embodiments; while non-removable in other embodiments.

In some embodiments, user 9000 may be able to breathe using breathing apparatus 400 when a mouth of user 9000 may be holding a mouth piece 401 of breathing apparatus 400. (See e.g., FIG. 4A for mouth piece 401.) Note, breathing apparatus 400 may be further detailed in the FIG. 4 series of figures and discussed below in the FIG. 4 series of figures discussion. (And other breathing apparatus embodiments may be addressed in a FIG. 20 series of figures, a FIG. 21 series of figures, and a FIG. 22 series of figures.)

When vessel 200 may be filled with liquid 101 to a level at or less than a maximum liquid level of vessel 200, user 9000 may soak the whole face 9010 or the portion thereof for a time period.

In some embodiments, contour 338 may comprise at least one sealing fin 350, and at least one pinch point 339. See e.g., FIG. 14K. At least one sealing fin 350 may be a wall like or dam like protrusion extending away from one or more of the surfaces of contour 338. At least one sealing fin 350 may comprise a function of providing additional sealing surface area for a complimentary frictional fit of some embodiments of vessel neck gasket 340, wherein elastomeric regions of vessel neck gasket 340 may be pressed against flat surfaces of at least one sealing fin 350. In the FIG. 14 series of figures, at least one pinch point 339 may comprise a projection extending away from one or more surfaces of contour 338. At least one pinch point 339 may extend away from the one or more surfaces of contour 338 less than how far at least one sealing fin 350 may extend away from the one or more surfaces of contour 338. See e.g., FIG. 14K. At least one pinch point 339 may comprise a function of providing an increased compression space for squeezing a portion of vessel neck gasket 340 material against complimentary pinch point(es) located on clamp 348. In some embodiments, contour 338 may comprise three pinch points 339. See e.g., FIG. 14K. In some embodiments, at least one sealing fin 350 may have a thickness, wherein a top (distal from contour 338 surfaces) of at least one sealing fin 350 may comprise one of the at least one pinch point 339. The two other pinch points 339, may be located one to each side of the pinch point 339 located at the top of at least one sealing fin 350. In some embodiments, these three pinch points may be termed first pinch point, second pinch point, and third pinch point, with the first pinch point being closest to internal volume 220, with the third pinch point being furthest from internal volume 220, and the second pinch point being disposed between the first and the second pinch points.

In some embodiments, at least one sealing fin 350 may be replaced with a channel embodiment (or at least one sealing fin 350 may be used in conjunction with a channel embodiment), wherein the channel may extend into contour 338, rather than away from contour 338 surfaces as with at least one sealing fin 350. However, without other modifications, such as a channel drainage means, at least one sealing fin 350 may be exemplary over sole channel embodiments because channels may accumulate liquid and debris, providing a source of possible contamination and sanitation issues.

In some such embodiments, neck-gasket-accommodator 335 may further comprise at least one lip 352. At least one lip 352 may extend in an opposite direction of at least one sealing fin 350 and on a distal portion of neck-gasket-accommodator 335 from internal volume 220. In some embodiments, at least one lip 352 may comprise a function of providing additional surface area to complimentary mate with a tab 355 of clamp 348. In some embodiments, at least one lip 352 may be provided with structural support from molded ribs or similar structures. In some embodiments, such ribs or similar support structures may be located on a bottom (ventral) side of neck-gasket-accommodator 335, exterior to internal volume 220. See e.g., FIG. 14K and FIG. 14N.

In some embodiments, attachment of vessel neck gasket 340 to a given vessel (e.g., vessel 200) may comprise the following structure and elements: vessel neck gasket 340, neck-gasket-accommodator 335 (a region of a given vessel), and the vessel neck gasket attachment means. See e.g., the FIG. 14 series of figures.

In some embodiments, vessel neck gasket 340 may comprise carrier 1449. Or alternatively, a given face soaking device may comprise carrier 1449. See e.g., FIG. 14E and/or FIG. 14F. Carrier 1449 may function to provide some rigidity and/or some mating structure to vessel neck gasket 340, wherein such provided rigidity and/or provided mating structures may assist in attaching vessel neck gasket 340 to neck-gasket-accommodator 335 (or to the vessel proximate to neck-gasket-accommodator 335). Carrier 1449 may be semi-rigid to rigid. In some embodiments, carrier 1449 may have a geometric structure which may generally approximate the overall shape of neck-gasket-accommodator 338 and may be complimentary to contour 338. For example, and without limiting the scope of the present invention, carrier 1449 may comprise an overall shape which may be may be concave or convex with a semi-round, a semi-oval, a U-shape, any other similar semicircular, semi-elliptical, or semi-oval shape, a regular or an irregular polygon or a semi-polygon shape that may approximate a complimentary overall shape of neck-gasket-accommodator 335 (e.g. contour 338).

In some embodiments, carrier 1449 may be integral with vessel neck gasket 340, in which carrier 1449 and vessel neck gasket 340 may be a single article of manufacture. In other embodiments, carrier 1449 may be a separate part from vessel neck gasket 340, wherein carrier 1449 may be attached to vessel neck gasket 340. Regardless of whether carrier 1449 and vessel neck gasket 340 may be integral or a subassembly, a union of carrier 1449 to vessel neck gasket 340 may form mating edge 343.

In some embodiments, such attachment of carrier 1449 to vessel neck gasket 340 may be removable, while in other embodiments, such attachment may be permanent. Such attachment may be by one or more of: solvent bonding, heat welding, ultrasonic welding, chemical adhesives/sealants, mechanical fasteners, and/or the like.

As noted, the union of vessel neck gasket 340 to carrier 1449 may result in mating edge 343. That is, a portion of the flexible, compressible, and/or elastomeric component of vessel neck gasket 340 may cover a portion of carrier 1449, wherein the interior surfaces of such physical contact between vessel neck gasket 340 and carrier 1449 may be attached to each other (either integrally or by the above noted attachment methods) and the exterior surface of that portion of vessel neck gasket 340 may then form mating edge 343. Thus, when the union of carrier 1449 and vessel neck gasket 340 may be placed (and pushed) into or onto contour 338, the flexible, compressible, and/or elastomeric component of vessel neck gasket 340 in physical contact with contour 338 may be compressed to form the primary water tight seal, wherein such compression may be increased by at the at least one pinch point and/or the additional surface area may be provided by at least one sealing fin 350. See e.g., FIG. 14N.

In some embodiments, the union of carrier 1449 and vessel neck gasket 340 may comprise an outside diameter which may be complimentary to inside diameters of contour 338, such that placement of the union of carrier 1449 and vessel neck gasket 340 into contour 338 may result in a frictional fit, wherein friction may hold the union of carrier 1449 and vessel neck gasket 340 in place to contour 338.

In some embodiments, the vessel neck gasket attachment means may comprise clamp 348. See e.g., FIG. 14E or FIG. 14F. In the FIG. 14 series of figures, clamp 348 may comprise a function of attaching the union of carrier 1449 and vessel neck gasket 340 to contour 338 of neck-gasket-accommodator 335. In some embodiments, such an attachment may be removable; while in other embodiments, such attachment may be permanent. In some exemplary embodiments, such an attachment may be by a frictional fit. In some embodiments, such a frictional attachment means may be removable; while in other embodiments, such a frictional attachment means may be permanent.

In some embodiments, clamp 348 may be constructed of a semi-rigid to rigid material of construction, such as a thermoformed plastic. In some embodiments, clamp 348 may have a geometric structure which may generally approximate the overall shape of neck-gasket-accommodator 338 and may be complimentary to contour 338. For example, and without limiting the scope of the present invention, clamp 348 may comprise an overall shape which may be may be concave or convex with a semi-round, a semi-oval, a U-shape, any other similar semicircular, semi-elliptical, or semi-oval shape, a regular or an irregular polygon or a semi-polygon shape that may approximate a complimentary overall shape of neck-gasket-accommodator 335 (e.g. contour 338). In some embodiments, clamp 348 may comprise two clamp terminal ends 358. See e.g., FIG. 14G or FIG. 14E.

In some embodiments, clamp 348 may comprise two exterior surfaces, an upper exterior surface 356, and a lateral exterior surface 357. See e.g., FIG. 14N. Upper exterior surface 356 and lateral exterior surface 357 may attach to each other at a common and continuous vertex. In some embodiments, upper exterior surface 356 and lateral exterior surface 357 may diverge from each other at an angle of 60 degrees to 110 degrees. In other embodiments, other angles of divergence may be measured between upper exterior surface 356 and lateral exterior surface 357. In some embodiments, clamp 348 may comprise a first complimentary sealing fin 353, a second complimentary sealing fin 354, and a complimentary pinch point 351. See e.g., FIG. 14N. First complimentary sealing fin 353, second complimentary sealing fin 354, and complimentary pinch point 351 may each extend away from upper exterior surface 356. First complimentary sealing fin 353, second complimentary sealing fin 354, and complimentary pinch point 351 may each extend away from upper exterior surface 356 by a different distance. In some embodiments, first complimentary sealing fin 353 may be longer than second complimentary sealing fin 354, and second complimentary sealing fin 354 may be longer than complimentary pinch point 351. Between first complimentary sealing fin 353 and second complimentary sealing fin 354 may be sufficient space to accommodate the thickness of at least one sealing fin 350. Between second complimentary sealing fin 354 and lateral external surface 357 may be sufficient space to accommodate a thickness of vessel neck gasket 340, which may be compressed and/or stretched when sandwiched between clamp 248 and neck-gasket-accommodator 335. See e.g., FIG. 14N.

In some embodiments, lateral exterior surface 357 may terminate in pull 364. See e.g., FIG. 14N. That is, pull 364 may be distal from the common and continuous vertex where upper exterior surface 356 and lateral exterior surface 357 may attach to each other. In some embodiments, pull 364 may be configured to be pulled on by user 9000 to release clamp 348 from neck-gasket-accommodator 335. In some embodiments, a portion of lateral exterior surface 357 and pull 364 may extend beyond at least one lip 352. In some embodiments, lateral exterior surface 357 may comprise tab 355. Tab 355 may protrude from an interior surface side of lateral exterior surface 357. Tab 355 may be configured to engage (e.g. hook onto) at least one lip 352 of neck-gasket-accommodator 335. See e.g., FIG. 14N.

When clamp 348 may be attached over the union of carrier 1449 and vessel neck gasket 340 to contour 338, first complimentary sealing fin 253 may directly oppose the first pinch point, complimentary pinch point 251 may directly oppose the second pinch point formed by the top of at least one sealing fin 350, and second sealing fin 254 may directly oppose the third pinch point. See e.g., FIG. 14N. Each of these three pairings may form regions for compressing portions of vessel neck gasket 340. Compressing portions of vessel neck gasket 340 between clamp 348 and contour 338 may form the primary water tight seal.

In some embodiments, clamp 348 may comprise an outside diameter which may be complimentary to inside diameters of contour 338, such that placement of clamp 348 into contour 338 may result in a frictional fit, wherein friction may hold clamp 348, as well as the union of carrier 1449 and vessel neck gasket 340, in place to contour 338. In some embodiments, installing clamp 348 over the union of carrier 1449 and vessel neck gasket 340 and into contour 338 may require squeezing each clamp terminal end 358 towards each other to place clamp 348 into place over the union of carrier 1449 and vessel neck gasket 340 and into contour 338, wherein release of the two clamp terminal ends 358 may then yield the frictional fit.

A FIG. 15 series of figures may comprise FIG. 15A through FIG. 15F. The FIG. 15 series of figures may depict a hinge embodiment how vessel neck gasket 340 may rotationally translate with respect to the vessel (e.g., vessel 200). FIG. 15A may depict a face soaking device with an alternative embodiment vessel neck gasket 340, wherein clamp 348 may swivel (pivot), shown from a perspective view. (A breathing apparatus, a head rest subassembly, a heater subassembly, and a gas diffuser may be removed.) FIG. 15B may depict the face soaking device from FIG. 15A, but wherein the vessel neck gasket 340 and the clamp 348 may be exploded from the vessel. FIG. 15C may depict the face soaking device from FIG. 15A, but shown from a front view, with a sectional line 15D-15D through vessel neck gasket 340 and clamp 348. FIG. 15D may depict a partial cross-sectional side view along sectional line 15D-15D. FIG. 15E may depict the face soaking device from FIG. 15A, but shown from a side (right) view, with a sectional line 15F-15F through the vessel. FIG. 15F may depict a transverse-width cross-sectional view along sectional line 15F-15F.

In some FIG. 15 series embodiments, clamp 348 may be attached to the vessel in a manner which permits rotational (i.e., pivot or hinge) movement at a place of attaching clamp 348 to the vessel, such as hinge motion. See e.g., FIG. 15B. In some embodiments, each terminal end 358 of this clamp 358 may comprise a pin 1559, i.e. clamp 348 may comprise two pins 1559. Each pin 1559 may point away from each other, i.e. each pin 1559 may extend from each terminal end 358, such that each pin 1559 may be disposed opposite of each other. Each pin 1559 may be captured by a pin receptacle 1560. Each pin receptacle 1560 may be located at a top of neck-gasket-accommodator 335, at each end of horizontal width 337. See e.g., FIG. 15B. At this top location, the pair of pin receptacles 1560 may be located in at least one of three regions of this top location: (1) extending into a wall thickness of at least one side wall 205 (depicted in FIG. 15B); (2) on exterior wall surface 202 (not depicted); or (3) on interior wall surface 203 (not depicted). When the pair of pin receptacles 1560 may be located at an exterior top location, clamp 348 may open towards the exterior of the vessel. When the pair of pin receptacles 1560 may be located at an interior top location, clamp 348 may open towards the interior of the vessel. When the pair of pin receptacles 1560 may be located a top location of within the wall thickness (e.g., as shown in FIG. 15B) of at least one side wall 205, clamp 348 may open towards the interior of the vessel or clamp 348 may open towards the exterior of the vessel. (When clamp 348 may be configured to open and/or close in the interior of vessel 200, lateral exterior surface 357 of clamp 348 may be deemed “lateral interior surface 357.” See e.g., FIG. 15F.)

In some embodiments, pin receptacles 1560 may be accessible via openings from (1) contour 338; (2) from exterior wall surface 202 (see e.g., FIG. 15F); (3) from interior wall surface 203; and/or (4) from rim 225.

In some embodiments, such a pivotable clamp 348 may then pivot downwards to form the primary water tight seal by pressing vessel neck gasket 340 against interior wall surface 203 of vessel 200, proximate to neck-gasket-accommodator 335. See e.g., FIG. 15D. In some embodiments, parallel and proximate to neck-gasket-accommodator 335 may be a channel 1561. Channel 1561 may be configured to receive a portion of vessel neck gasket 340, to create both a frictional fit and the primary water tight seal. In some embodiments, vessel neck gasket 340 may comprise a molded region (not depicted) to be complimentary with fitting into channel 1561. In some embodiments, such a molded region of vessel neck gasket 340 may comprise at least one micro fin protrusion to enhance friction and the primary water tight seal. In some exemplary embodiments, channel 1561 may be located on interior wall surface 203 side versus exterior wall surface 202, which may facilitate proper liquid 101 drainage towards internal volume 220. See e.g., FIG. 15D. In some embodiments, channel 1561 may be located on exterior wall surface 202 side (this embodiment not depicted).

In some embodiments, channel 1561 may be configured to receive the portion of vessel neck gasket 340 (which may be molded) and a portion of clamp 348, to create both a frictional fit and the primary water tight seal. See e.g., FIG. 15D. The portion of clamp 348 may be tooth 1563. In some embodiments, tooth 1563 may comprise at least one micro fin protrusion 1565 to enhance friction and the primary water tight seal. See e.g., FIG. 15D.

In some embodiments, clamp 348 may be a subassembly with gasket 340. See e.g., FIG. 31. In this embodiment, this subassembly of clamp 348 and vessel neck gasket 340 may be press fit into contour 338 of neck-gasket-accommodator 335. Mating edge 343 may run around bottom and side edges of clamp 348 and with a remainder of gasket 340 being disposed in an inside diameter arc of clamp 348. Clamp 348 may be rigid to semi-rigid. Vessel neck gasket 340 and mating edge 343 may be elastomeric materials, such as, but not limited to neoprene. Each clamp terminal end 358 may comprise a freely rotating hook lock 3101, which may be received into a respective receiving groove 3102, such that clamp 348 with vessel neck gasket 340 may be pressed down into contour 338, such that mating edge 343 is forming the primary water tight seal with contour 338, and then hook locks 3101 may be rotated into place within receiving groove 3102 to lock clamp 348 and vessel neck gasket 340 into place. Each receiving groove 3102 may comprise a tab 3103 to removably engage the interior open space 3104 of each hook lock 3101. The pair of receiving grooves 3102 may bound horizontal width 337. See e.g., FIG. 31.

At least one vessel-tube-hose-connector 430 may be in gas communication with air and may be configured for respiratory gas movement. In some embodiments, at least one vessel-tube-hose-connector 430 may function as a gas vent. As shown in FIG. 4A, at least one hose 420 or at least one tubing 420 may be two hoses 420 or two tubes 420. As shown in FIG. 4A, at least one vessel-tube-hose-connector 430 may be two vessel-tube-hose-connectors 430, i.e. one associated with each hose 420 or tube 420. See e.g., FIG. 4A.

In some embodiments, mouth piece 401 may comprise a mouthing portion 403. See e.g., FIG. 4A. Mouthing portion 403 may be configured to be held by the mouth of user 9000, such that a watertight seal between lips of user 9000 and mouthing portion 403 may be formed when user 9000 may hold mouthing portion 403 within the mouth. In some embodiments, mouthing portion 403 may comprise at least one protrusion. The at least one protrusion may be configured to be held by teeth of user 9000. In some embodiments, mouthing portion 403 may be constructed of a soft elastomer. In some embodiments, mouthing portion 403 of mouth piece 401 may be constructed of silicone, rubber (either natural or synthetic), and/or the like.

In some embodiments, mouth piece 401 may comprise a purge valve. The purge valve may be configured to operate as a one way check valve. The purge valve may allow liquid 101 (and/or saliva) to leave mouth piece 401 but may not permit liquid 101 to enter mouth piece 401 by way of the purge valve.

In some embodiments, the purge valve may be of a typical one way check valve used in various human breathing devices, such as flapper valves or spring loaded check valves. A natural or resting state of the purge valve may be closed. The purge valve may only open to release liquid 101 (and/or saliva) upon a sufficiently strong exhale from user 9000 to overcome the means used for maintaining the valve closed. In some embodiments, the purge valve may be located on a ventral (bottom) portion of mouth piece 401, i.e. facing base 215 of vessel 200. In some embodiments, the purge valve may be located at other locations on mouth piece 401.

Note, a hose 420 and/or a tubing 420 as used herein, may refer to hose 420 or tubing 420 that may be capable of permitting user 9000 to breathe while hose 420 or tubing 420 may be subjected to liquid 101 pressure upon an outside diameter of hose 420 or tubing 420, without hose 420 or tubing 420 kinking or collapsing under that pressure. Such a hose 420 and/or tubing 420 may be known in the art as breathing hosing, as breathing tubing, and/or the like.

In some embodiments, mouth piece 401 may comprise at least one connection end 405. At least one hose 420 or the at least one tubing 420 may comprise first terminal end 421 and second terminal end 422 disposed opposite of the first terminal end 421. At least one connection end 405 may be configured to connect to first terminal end 421 forming a coupling. This coupling may be configured to permit swivel rotational movement between at least one connection end 405 and first terminal end 421 that may be connected to at least one connection end 405. Such swivel rotational movement may provide increased comfort to user 9000. This coupling may be water tight. See e.g., FIG. 4A, FIG. 4C, and FIG. 4E.

In some embodiments, this swivel capacity that may be shown in Detail 4E and in FIG. 4E, and this water tight capacity of this coupling may be facilitated by a snap fit, a friction fit, a tongue (i.e. flange) and groove fit, and by use of O-rings, washers, and/or gaskets. Such O-rings, washers, and/or gaskets may be separate or integral with at least one hose 420 or the at least one tubing 420. Such O-rings, washers, and/or gaskets may be proximate to first terminal end 421. For example, and without limiting the scope of the present invention, in some embodiments, this may be three inches or less; or three inches or less down to 1/32 of an inch.

In some embodiments the connection of at least one connection end 405 to first terminal end 421 may be a removable connection. In some embodiments the connection of at least one connection end 405 to first terminal end 421 may be a non-removable connection.

In some embodiments, second terminal end 422 may connect to at least one vessel-tube-hose-connector 430. See e.g., Detail 4D of FIG. 4C and FIG. 4D. At least one vessel-tube-hose-connector 430 may be substantially constructed from one or more elastomeric materials, such as, but not limited to various rubbers and/or silicones. In some embodiments, at least one vessel-tube-hose-connector 430 may be substantially constructed from a thermoformed plastic. At least one vessel-tube-hose-connector 430 may connect to at least one grommet-accommodating-contour 470 of vessel 200. See e.g., FIG. 4G, FIG. 4H, FIG. 4I, and FIG. 4J. In some embodiments, a portion of at least one vessel-tube-hose-connector 430 may be configured to be captured and held in place by at least one grommet-accommodating-contour 470. In some embodiments, at least one vessel-tube-hose-connector 430 may be configured to permit swivel rotational movement between second terminal end 422 and at least one vessel-tube-hose-connector 430. In some embodiments, this portion of at least one vessel-tube-hose-connector 430 that may accommodate such rotational movement may be an opening 431. In exemplary embodiments, opening 431 to at least one end of at least one vessel-tube-hose-connector 430 may be in gaseous communication with air. Where at least one vessel-tube-hose-connector 430 may be captured by at least one grommet-accommodating-contour 470, a water tight seal may be formed. See e.g., FIG. 4H.

In some embodiments, this swivel capacity and/or the water tight capacity of where second terminal end 422 in at least one vessel-tube-hose-connector 430 may be captured, may be facilitated by a snap fit, a friction fit, a tongue and groove fit, and by use of grommets, O-rings, washers, and/or gaskets.

In some embodiments the connection of at least one vessel-tube-hose-connector 430 to second terminal end 422 may be a removable connection. In some embodiments the connection of at least one vessel-tube-hose-connector 430 to second terminal end 422 may be a non-removable connection.

In some embodiments, second terminal end 422 of at least one hose 420 or at least one tubing 420 may be inserted (or at least partially inserted) into opening 431 of at least one vessel-tube-hose-connector 430. Such an insertion may be facilitated by second terminal end 422 tapering. Such an insertion may form a frictional fit between second terminal end 422 and at least one vessel-tube-hose-connector 430, and in particular with at least portions of opening 431. Such an insertion may be removable or may be permanent in various embodiments.

In some embodiments, opening 431 may run from an interior side 433 (see e.g., FIG. 4M) of at least one vessel-tube-hose-connector 430 to an exterior side 435 (see e.g., FIG. 4N) of at least one vessel-tube-hose-connector 430. See e.g., FIG. 4L.

In some embodiments, this cavity may comprise at least some surface area that may be complimentary to at least some surface area of second terminal end 422. Such complimentary surfaces areas (or portions thereof) may permit a frictional fit between the at least some surface area of second terminal end 422 and the at least some surface area of the cavity of opening 431. Such complimentary surfaces areas (or portions thereof) may permit rotational movement between the at least some surface area of second terminal end 422 and the at least some surface area of the cavity of opening 431. The surface area of opening 431 may form a shape that may substantially match a shape of the surface area of second terminal end 422, such that a frictional fit between the at least some surface area of second terminal end 422 and the at least some surface area of the cavity of opening 431 may be formed. See e.g., FIG. 4J.

In some embodiments, opening 431 may be a cylindrical cavity. See e.g., FIG. 4M and FIG. 4N. In such embodiments, this cylindrical cavity may comprise at least some surface area that may be complimentary to at least some surface area of second terminal end 422, permitting a frictional fit between the at least some surface area of second terminal end 422 and the at least some surface area of the cylindrical cavity of opening 431. See e.g., FIG. 4J.

In some embodiments, this cavity of opening 431 may be tapered to facilitate the frictional fit between the at least some surface area of second terminal end 422 and the at least some surface area of the cylindrical cavity of opening 431.

In some embodiments, second terminal end 422 may be inserted through opening 431 such that second terminal end 422 may protrude beyond exterior side 435. This embodiment is not shown in the FIG. 4 figures.

In some embodiments, a bottom of this cavity of opening 431 may be sloped such that liquid 101 in this cavity may gravity drain into internal volume 220 when at least one vessel-tube-hose-connector 430 may be attached to at least one grommet-accommodating-contour 470. In some embodiments, a bottom of this cavity of opening 431 may be sloped such that liquid 101 in this cavity may gravity drain into catch basin 230 when at least one vessel-tube-hose-connector 430 may be attached to at least one grommet-accommodating-contour 470.

In some embodiments, at least one vessel-tube-hose-connector 430 may connect to at least one grommet-accommodating-contour 470 of vessel 200. Such a connection may be how breathing apparatus 400 may be (removably) connected to vessel 200. See e.g., FIG. 4B, FIG. 4C, FIG. 4D, FIG. 4G, FIG. 4I, and FIG. 4J. In some embodiments, at least one vessel-tube-hose-connector 430 may be an elastomeric grommet with a shape that may be complimentary for a frictional fit into at least one grommet-accommodating-contour 470. In some embodiments, at least one vessel-tube-hose-connector 430 may be a thermoformed plastic grommet with a shape that may be complimentary for a frictional fit into at least one grommet-accommodating-contour 470. See e.g., FIG. 4K through FIG. 4Q for an example shape of at least one vessel-tube-hose-connector 430.

In some embodiments, at least one grommet-accommodating-contour 470 may be a contour of complimentary surface area sized to frictionally grip at least a portion of at least one vessel-tube-hose-connector 430. See e.g., FIG. 4A and FIG. 4H for an example contour of at least one grommet-accommodating-contour 470. In some embodiments, at least one grommet-accommodating-contour 470 may be a contour of complimentary surface area sized to frictionally grip at least a bottom portion of the at least one vessel-tube-hose-connector 430. See e.g., FIG. 4A and FIG. 4H for the contour of at least one grommet-accommodating-contour 470.

In some embodiments, at least one grommet-accommodating-contour 470 may be a cutout in rim 225 of vessel 200 or in top opening 226 of vessel 200. Or in some embodiments, the contour of may be formed from a cutout in rim 225 of vessel 200 or in top opening 226 of vessel 200. See e.g., FIG. 4A and FIG. 4H for the contour of at least one grommet-accommodating-contour 470.

That is, in some embodiments, at least one grommet-accommodating-contour 470 may extend from rim 225 of vessel 200 or from top opening 226 of vessel 200 downwards into at least one wall 201 for some proximate distance, forming a shape of this contour. For example, and without limiting the scope of the present invention, this proximate distance may be three inches or less in some embodiments. While this shape of this contour of at least one grommet-accommodating-contour 470 as shown in FIG. 4A and FIG. 4H may be curved approximating a cylindrical or conical shape, this shape may actually be determined from a complimentary shape of at least one vessel-tube-hose-connector 430 (or at least a portion thereof) such that at least some portion of at least one vessel-tube-hose-connector 430 may be inserted into at least one grommet-accommodating-contour 470 and forming a frictional fit.

In some embodiments, this cutout or this contour of at least one grommet-accommodating-contour 470 may be sloped such that liquid 101 may tend to drain towards internal volume 220. In some embodiments, this cutout or this contour of at least one grommet-accommodating-contour 470 may be sloped such that liquid 101 may tend to drain towards catch basin 230.

In some embodiments, at least one grommet-accommodating-contour 470 may be formed from at least one wall 201 in a region proximate to rim 225, such that inner vessel wall (e.g., interior wall surface 203) may be continuous with an outer vessel wall (e.g. exterior wall surface 202) or such that the inner vessel wall may extend beyond the outer vessel wall to minimize the liquid entering between such vessel walls. See e.g., FIG. 4D.

It should be noted that use of the word “cutout” in this context may be a reference to surface geometry of at least one grommet-accommodating-contour 470 depicted in FIG. 4A and FIG. 4H and not necessarily a reference to actually cutting out material from at least one wall 201. Rather in some embodiments, this cutout or this contour of at least one grommet-accommodating-contour 470 may be molded.

In some embodiments, this cutout or this contour of at least one grommet-accommodating-contour 470 may be exteriorly bounded by an exterior side containment lip 471 that may extend substantially perpendicular from a surface area of this cutout or this contour. See e.g., FIG. 4J. That is, this exterior side containment lip 471 may be located closer to exterior wall surface 202 than to interior wall surface 203.

In some embodiments, at least one vessel-tube-hose-connector 430 may comprise a butting-ring 437 that may be complimentary to exterior side containment lip 471. See e.g., FIG. 4K. In some embodiments, butting-ring 437 may be a partial ridge or a partial ring of material, circumscribing a bottom of at least one vessel-tube-hose-connector 430. See e.g., FIG. 4Q. In some embodiments, butting-ring 437 may be closer to exterior side 435 than to interior side 433. See e.g., FIG. 4Q. In some embodiments, butting-ring 437 may contact an interior portion of exterior side containment lip 471, when at least one vessel-tube-hose-connector 430 may be inserted into the at least one grommet-accommodating-contour 470. See e.g., FIG. 4J. That is, in some embodiments, when at least one vessel-tube-hose-connector 430 may be inserted into the at least one grommet-accommodating-contour 470, exterior side containment lip 471 may help to frictionally hold at least one vessel-tube-hose-connector 430 by exterior side containment lip 471 removably mating with butting-ring 437 and/or trapping butting-ring 437.

In some embodiments, this cutout or this contour of at least one grommet-accommodating-contour 470 may be interiorly bounded by an interior side containment lip 473 that may extend substantially perpendicular from the surface area of this cutout or this contour. See e.g., FIG. 4A and FIG. 4H. That is, this interior side containment lip 473 may be located closer to interior wall surface 203 than to exterior wall surface 202.

In some embodiments, at least one vessel-tube-hose-connector 430 may comprise an interior-butting-ring 439 that may be complimentary to interior side containment lip 473. See e.g., FIG. 4K. In some embodiments, interior-butting-ring 439 may be a partial ridge or a partial ring of material, circumscribing the bottom of at least one vessel-tube-hose-connector 430. See e.g., FIG. 4Q. In some embodiments, interior-butting-ring 439 may be closer to interior side 433 than to exterior side 435. See e.g., FIG. 4Q. In some embodiments, interior-butting-ring 439 may contact an interior portion of interior side containment lip 473, when at least one vessel-tube-hose-connector 430 may be inserted into the at least one grommet-accommodating-contour 470. That is, in some embodiments, when at least one vessel-tube-hose-connector 430 may be inserted into the at least one grommet-accommodating-contour 470, interior side containment lip 473 may help to frictionally hold at least one vessel-tube-hose-connector 430 by interior side containment lip 473 removably mating with interior-butting-ring 439 and/or trapping interior-butting-ring 439.

In some embodiments, this cutout of at least one grommet-accommodating-contour 470 may comprise a surface area. In some embodiments, this surface area may comprise a bottom. In some embodiments, located on this bottom may comprise at least one weep-hole 475. In some embodiments, at least one weep-hole 475 may pass entirely through at least one wall 201 from which at least one grommet-accommodating-contour 470 may be formed. In some embodiments, this at least one weep-hole 475 may permit liquid 101 on the surface area (of at least one grommet-accommodating-contour 470) to gravity drain through the at least one weep-hole 475. In some embodiments, such liquid 101 may drain into catch basin 230. See e.g., FIG. 4D and FIG. 4J.

In some embodiments, this bottom of the surface area of the cutout of at least one grommet-accommodating-contour 470 may comprise at least one drain-channel 477. In some embodiments, at least one drain-channel 477 may permit liquid 101 on the surface area to gravity drain from the at least one drain-channel 477 (into internal volume 220). In some embodiments, at least one drain-channel 477 may be closer to interior wall surface 203 than to exterior wall surface 202. In some embodiments, such liquid 101 may drain into internal volume 220. See e.g., FIG. 4H and FIG. 4A. In some embodiments, at least one drain-channel 477 may cut through interior side containment lip 473 of this cutout of at least one grommet-accommodating-contour 470. See e.g., FIG. 4H and FIG. 4A.

In some embodiments, at least one vessel-tube-hose-connector 430 may comprise a connector-rim 441. In some embodiments, connector-rim 441 may run along a top of at least one vessel-tube-hose-connector 430. See e.g., FIG. 4K and FIG. 4L. In some embodiments, when at least one vessel-tube-hose-connector 430 may be (removably) inserted into at least one grommet-accommodating-contour 470, then connector-rim 441 may be substantially even with rim 225 of vessel 200. See e.g., FIG. 4G, FIG. 4I, and FIG. 4J. In some embodiments, when at least one vessel-tube-hose-connector 430 may be (removably) inserted into at least one grommet-accommodating-contour 470, then connector-rim 441 may be below rim 225 of vessel 200 (not depicted). In some embodiments, when at least one vessel-tube-hose-connector 430 may be (removably) inserted into at least one grommet-accommodating-contour 470, then connector-rim 441 may be above rim 225 of vessel 200 (not depicted).

In some embodiments, user 9000 may insert a portion of at least one finger into opening 431 to pull at least one vessel-tube-hose-connector 430 from at least one grommet-accommodating-contour 470 (e.g., by pulling upwards away from at least one base 215). When at least one vessel-tube-hose-connector 430 may be connected to at least one tubing 420 or at least one hose 420, then removing at least one vessel-tube-hose-connector 430 may also remove at least one tubing 420 or at least one hose 420 from at least one grommet-accommodating-contour 470.

In FIG. 22F an alternative embodiment of at least one vessel-tube-hose-connector 430 may be shown, where here in FIG. 22F the at least one vessel-tube-hose-connector may be denoted with reference numeral 2231. In some embodiments, at least one vessel-tube-hose-connector 2231 may comprise an independent (separate) finger pull ring 2232 for lifting at least one vessel-tube-hose-connector 2231 out of at least one grommet-accommodating-contour 2234. At least one grommet-accommodating-contour 2234 of FIG. 22F may be the equivalent to at least one grommet-accommodating-contour 470 of the FIG. 4 series. That is, with at least one vessel-tube-hose-connector 2231, rather than using opening 431 as a finger pull, the independent (separate) finger pull ring 2232 may be used.

Turning back to the FIG. 4 series of figures, in some embodiments, a mounting location for at least one vessel-tube-hose-connector 430 may be at least one grommet-accommodating-contour 470 of vessel 200. In some embodiments, the mounting location may be above the maximum liquid level of vessel 200. In some embodiments, the mounting location for at least one vessel-tube-hose-connector 430 may be below the maximum liquid level of vessel 200. In both embodiments, at least one vessel-tube-hose-connector 430 may be still in gas communication with the air and how at least one vessel-tube-hose-connector 430 may be captured by at least one grommet-accommodating-contour 470 may be water tight.

In some embodiments, breathing apparatus 400 may comprise two vessel-tube-hose-connectors 430 and two hoses 420 or two tubes 420, in addition to a single mouth piece 401. See e.g., FIG. 4A and FIG. 4B. Each such hose 420 or each such tube 420 may comprise two terminal ends, first terminal end 421 and second terminal end 422 disposed opposite of first terminal end 421. Mouth piece 401 may comprise two connection ends 405. First terminal end 421 of each hose 420 or each tube 420 may connect to one respective connection end 405. Second terminal end 422 of each hose 420 or each tube 420 may connect to each respective vessel-tube-hose-connector 430. Each vessel-tube-hose-connector 430 may mount to a location on vessel 200. In some embodiments, this mounting location may be at least one grommet-accommodating-contour 470; wherein in some embodiments, there may be two grommet-accommodating-contours 470. In some embodiments, these two at least one grommet-accommodating-contours 470 may be located on opposing side walls 205 (e.g., first side wall 206 and third side wall 208). See e.g., FIG. 4A. Having two hoses 420 or tubes 420, two vessel-tube-hose-connectors 430, and two grommet-accommodating-contours 470 may provide a safety redundancy.

In some embodiments, each connection end 405 of mouth piece 401 may be disposed opposite of each other on mouth piece 405. See e.g., FIG. 4A. In some embodiments, each connection 405 and mouthing portion 403 may be about 120 degrees apart from each other, i.e. about equally oriented from each other (this embodiment may not be depicted).

In some embodiments, mounting second terminal end 422 of each hose 420 or each tube 420 to each vessel-tube-hose-connector 430, to some structure of vessel 200, and/or to a given head rest subassembly may be accomplished by a snap fit, a friction fit, a tongue (flange) and groove fit, use of grommets, O-rings, washers, and/or gaskets, solvent bonding, heat welding, ultrasonic welding, chemical adhesives/sealants, and the like. In some embodiments, second terminal end 422 of each hose 420 or each tube 420 may be mounted to a given port in a given vessel embodiment (e.g., vessel 200).

In some embodiments, at least one hose 420 or the at least one tubing 420 may be flexible, kink resistant, and sufficiently strong to not collapse under pressure from liquid 101 in internal volume 220. In some embodiments, such hose 420 and/or tubing 420 flexibility may permit user 9000 to place mouth piece 401 (e.g., mouthing portion 403) into the mouth of user 9000 while the mouth may be in the air and then user 9000 may insert the held mouth piece 401 into liquid 101 and then to breathe through breathing apparatus 400.

In some embodiments, at least one hose 420 or the at least one tubing 420 may be corrugated or non-corrugated in other embodiments. Corrugated hose 420 or corrugated tubing 420 may be both flexible and kink resistant. Kink resistance may also be achieved with reinforcement to hose 420 or to tubing 420, such as with textile braiding or polymer braiding. Kink resistance may also be achieved by: increasing the durometer of hose 420 material formulation or of tubing 420 material formulation; by having a star shaped inside diameter cross section of hose 420 or tubing 420; and/or by increasing a thickness of hose 420 material or tubing 420 material (i.e., a distance between an outside diameter and an inside diameter of hose 420 or tubing 420).

In some embodiments, the pressure exerted by liquid 101 upon hose 420 or the tubing 420 may be governed by a height (i.e. head) of liquid 101 within internal volume 220 and the local atmospheric pressure which may press upon liquid 101 within internal volume 220. For example, and without limiting the scope of the present invention, in some embodiments, the head may be 24 inches of liquid or less. In some embodiments, liquid 101 may be water, oil, combinations thereof; and with varying degrees of salinity, i.e. saline solutions. In other embodiments liquid 101 pressure may be greater or less.

In some embodiments, at least one hose 420 or the at least one tubing 420 may be substantially extruded and/or molded. In some embodiments, at least one hose 420 or the at least one tubing 420 may be constructed of one or more of the group selected from: PVC, rubber, fluor polymers, neoprene, polypropylene, polyethylene, and/or any other material suitable for use at allowing the user to breathe while the material may be submerged and under liquid 101 pressure. In some embodiments, a polymeric and/or elastomeric material used for at least one hose 420 or the at least one tubing 420 may be of a food grade or of a medical grade. Such a hose 420 or a tubing 420 before use by user 9000 may be cured to a point where offensive, smelly, and potentially harmful outgassing may be minimized.

Note, in some embodiments, breathing apparatus 400 may be rotated and/or articulated into a raised configuration, wherein mouth piece 401 may be higher than any second terminal end 422. When breathing apparatus 400 may be rotated into such a raised configuration, liquids 101 (and/or saliva) within breathing apparatus 400 may drain naturally via gravity and out of at least one vessel-tube-hose-connector 430 and into catch basin 230. Such rotation may be about each at least one vessel-tube-hose-connector 430 that may be removably coupled to a given at least one grommet-accommodating-contour 470.

In some embodiments, a breathing apparatus may comprise a hollow conduit having a first end and a second end. At least one of the first and second ends may be open (e.g. the second end). An third opening into the conduit may be disposed between the first open end and the second end of the conduit. A mouthpiece may be connected to the third opening such that user 9000 may place the person's mouth on the mouthpiece and breathe through the conduit with air passing between the mouthpiece and at least one of the first and second open ends of the conduit. The conduit may be otherwise sealed tight so that no liquid 101 may enter the conduit other than through the mouthpiece and at least one of the first and second ends of the conduit. The conduit of the apparatus may be shaped in such a manner that the first and second ends are generally co-axial, but where at least some of the conduit between the first and second ends may not be co-axial with the first and second ends. In an exemplary embodiment, the conduit will be shaped as shown in FIG. 4A and FIG. 4C. However, different shapes that accomplish the purpose of the shape shown in FIG. 4A and FIG. 4C are within the scope of some embodiments of this invention. For example, instead of the conduit curving, the conduit may be bent at sharp angles. The first and second ends of the conduit may be attached to the vessel (e.g., vessel 200) such that the conduit, as a whole, may swivel around the axis of the first and second ends, and such that the at least one open end may be completely above any liquid contained in the vessel. The mouthpiece may be arranged such that the mouthpiece and the part of the conduit to which the mouthpiece may be connected is not co-axial with the first and second ends of the conduit, but may offset a predetermined distance from that axis. Thus, when the conduit may be rotated about the axis through the first and second ends of the conduit, the resulting rotation of the mouthpiece may describe a circle about the axis of the first and second ends of the conduit. The offset of the mouthpiece from the axis of the first and second ends may allow user 9000 to place the user's 9000 mouth on the mouthpiece with the mouthpiece out of liquid 101 in the vessel, and then move the user's 9000 head such that the face 9010 and/or head of user 9000 may be at least partially submerged into liquid 101 in the vessel while user 9000 may be able to breathe through the mouthpiece and conduit. Other elements and features recited in this specification can be added to the breathing apparatus as desired.

Alternatively, the breathing apparatus may comprise a hollow conduit between the mouthpiece and the first open end such that there may be continuous open conduit between the mouthpiece and the first open end, and a guide that may not necessarily be hollow between the mouthpiece and the second end of the breathing device. Since breathing may be accomplished through only one side, it is not required that the other side be hollow. Instead, one side may simply be a shaped guide that need not be open for breathing. The first end of the breathing apparatus (which is open) and the second end of the breathing apparatus (which may be a simple guide) may be coaxial. This simple guide may be a rigid to semi-rigid elongate member, and may be insulated when this simple guide may be a metal.

FIG. 20A and FIG. 20B may depict independent breathing apparatus (2000 and 2050, respectively) that might not be coupled to (i.e., attached to or connected to) a given vessel (e.g., vessel 200); nor to any other given face soaking device component. Note in such embodiments, a system may comprise a given face soaking device along with an independent breathing apparatus (e.g., 2000 and 2050). FIG. 20A may depict a cross-sectional view of a face soaking device in use by user 9000, depicting an independent breathing apparatus 2000. FIG. 20B may depict a cross-sectional view of a face soaking device in use by user 9000, depicting an independent breathing apparatus 2050. Independent breathing apparatus 2000 may differ from independent breathing apparatus 2050, in that independent breathing apparatus 2000 may comprise two hoses 420 or tubes 420; while independent breathing apparatus 2050 may comprise one hose 420 or tube 420.

In FIG. 20A and FIG. 20B, in some embodiments, independent breathing apparatus 2000 and 2050 may comprise mouth piece 401, at least one exit port 2001, and at least one hose 420 or at least one tubing 420. At least one hose 420 or at least one tubing 420 may connect to mouth piece 401. Mouth piece 401 may be configured to be held by the mouth of user 9000. At least one exit port 2001 may be in gas communication with air and may be configured for respiratory gas movement. In some embodiments, at least one exit port 2001 may function as the gas vent. As shown in FIG. 20A, at least one hose 420 or at least one tubing 420 may be two hoses 420 or two tubes 420, with two exit ports 2001. As shown in FIG. 20B, at least one hose 420 or at least one tubing 420 may be one hose 420 or one tube 420; and with one exit port 2001.

In some embodiments, mouth piece 401 may comprise at least one connection end 405. At least one hose 420 or the at least one tubing 420 may comprise first terminal end 421 and second terminal end 422 disposed opposite of the first terminal end 421. At least one connection end 405 may be configured to connect to first terminal end 421 forming the coupling. This coupling may be configured to permit swivel rotational movement between at least one connection end 405 and first terminal end 421 that may be connected to at least one connection end 405. Such swivel rotational movement may provide increased comfort to user 9000. This coupling may be water tight.

In some embodiments, at least one exit port 2001 may be located at or proximate to second terminal end 422. For example, and without limiting the scope of the present invention, such a proximate distance may be within three inches of second terminal end 422. In other embodiments, this proximate distance may be greater than three inches. In some embodiments, second terminal end 422 may terminate in at least one exit port 2001.

In some embodiments, a length of at least one hose 420 or at least one tubing 420 may be such, that when independent breathing apparatus 2000 or 2050 may be in use by user 9000, as depicted in FIG. 20A and FIG. 20B, that at least exit port 2001 may be located above rim 225 and/or above the maximum liquid level, such that at least exit port 2001 may be located in the atmospheric environmental air.

In some embodiments, at least one hose 420 or at least one tubing 420 may be semi-rigid to rigid, such that second terminal end 422 may not bend back towards first terminal end 421 under the weight of at least one hose 420 or at least one tubing 420.

In some embodiments, independent breathing apparatus 2000 and/or 2050 might not be attached to vessel 200 (nor to other vessel embodiments), nor to head rest subassembly 500 (nor to other head rest subassembly embodiments). In some embodiments, independent breathing apparatus 2000 and/or 2050 might not be attached to user 9000, aside from the removable holding of mouth piece 401 by user's 9000 mouth. In some embodiments, independent breathing apparatus 2000 and/or 2050 may be removably attached to user 9000 and/or to vessel 200 (or to other vessel embodiments). For example, and without limiting the scope of the present invention, such removable attachment may be accomplished by straps and/or clips.

Aside from differences noted above, in some embodiments, independent breathing apparatus 2000 and independent breathing apparatus 2050 may be substantially similar to breathing apparatus 400 embodiments, in terms of functionality (e.g. facilitating respiratory gas movement of user 9000) and/or in terms of structure (e.g. hollow tubes or hollow hoses, mouthpiece 401, inclusion of the purge valve in some embodiments, and/or the like).

A FIG. 21 series of figures may comprise FIG. 21A through FIG. 21E. This FIG. 21 series of figures may depict embodiments of a breathing apparatus that may be combined with a head rest subassembly. FIG. 21A may depict a face soaking device embodiment, wherein a breathing apparatus may be incorporated (combined) into a head rest subassembly, shown from a perspective view, with a partial cutout view of the vessel. This may be combination breathing apparatus and head rest subassembly 2100.

FIG. 21B may depict combination breathing apparatus and head rest subassembly 2100, but from a top view. FIG. 21C may depict combination breathing apparatus and head rest subassembly 2100, but from a front view. And a sectional line 21E-21E may be shown in FIG. 21C through combination breathing apparatus and head rest subassembly 2100. FIG. 21D may depict combination breathing apparatus and head rest subassembly 2100, but from an exploded perspective view.

FIG. 21E may depict combination breathing apparatus and head rest subassembly 2100, showing the view along sectional line 21E-21E, which may show a longitudinal side cross sectional view of combination breathing apparatus and head rest subassembly 2100.

In some embodiments, combination breathing apparatus and head rest subassembly 2100 may comprise a breathing apparatus and a head rest subassembly into a single subassembly. The breathing apparatus may comprise: mouth piece 401 and at least one hose 420 or at least one tubing 420. In some embodiments, mouth piece 401 and at least one hose 420 or at least one tubing 420 may be as discussed above in the FIG. 4 series of figures discussion. The head rest subassembly may comprise support member 501, comfortable exterior surface 502, a height adjust means, and a forwards-backwards adjust means. In some embodiments, support member 501, comfortable exterior surface 502, the height adjust means, and the forwards-backwards adjust means may be as described and discussed below in the FIG. 5 series of figures discussion (discussed below) and in the FIG. 23 series of figures discussion (discussed after the FIG. 6 series of figures discussion below).

In combination breathing apparatus and head rest subassembly 2100 embodiments, support member 501 may be hollow elongate member. See e.g., FIG. 21D. A substantial portion of a length of at least one hose 420 or at least one tubing 420 may be housed within the hollow elongate member of support member 501. In some embodiments, mouth piece 401 may protrude from sixth terminal end 2302 of the hollow elongate member of support member 501. In some embodiments, an outside diameter of at least one hose 420 or at least one tubing 420 may be small enough as compared against an inside diameter of the hollow elongate member of support member 501, that at least one hose 420 or at least one tubing 420 may be housed and/or slide within the hollow elongate member of support member 501. Such sliding may permit vertical adjustments in a height of mouth piece 401 with respect to at least one base 215 (or bottom interior surface 217).

In some embodiments a length of at least one hose 420 or at least one tubing 420 may be less than a length of the hollow elongate member of support member 501. In such embodiments, second terminal end 422 of at least one hose 420 or at least one tubing 420 may not protrude beyond fifth terminal end 2301 of the hollow elongate member of support member 501. In some such embodiments, at least one hose 420 or at least one tubing 420 may not comprise common slots 2101. See e.g., FIG. 21D.

In some embodiments the length of at least one hose 420 or at least one tubing 420 may be longer than the length of the hollow elongate member of support member 501. In such embodiments, second terminal end 422 of at least one hose 420 or at least one tubing 420 may protrude beyond fifth terminal end 2301 of the hollow elongate member of support member 501. In some such embodiments, at least one hose 420 or at least one tubing 420 may comprise common slots 2101.

In some embodiments, the hollow elongate member of support member 501 may comprise two bends (with two angles) an upper bend (and upper angle) along with a lower bend (and lower angle). In some embodiments, at least one hose 420 or at least one tubing 420 may comprise at least one bend, a complimentary lower bend (lower angle). In some embodiments, at least one hose 420 or at least one tubing 420 may comprise at least one bend, a complimentary upper bend (upper angle). In some embodiments, the upper bend may be bend 2315. In some embodiments, the upper angle may be angle 2380 (see e.g., FIG. 23D).

Regions closer to fifth terminal end 2301 of the hollow elongate member of support member 501 and closer to second terminal end 422 of at least one hose 420 or at least one tubing 420 may be secured and/or attached to a given vessel (e.g., vessel 200). Such attachment may be as described in the FIG. 23 series of figures discussion below relating to head rest subassembly 2300. Such attachment may comprise, in some embodiments, friction clamp 2322, cover 2370, common slots 2101, and recessed channel 2350. In combination breathing apparatus and head rest subassembly 2100 common slots 2101 may replace slot 2320 from head rest subassembly 2300 in support member 501, but may serve a same function and with a same general structure as slot 2320. However, common slots 2101 may be present in two opposing locations on at least one hose 420 or at least one tubing 420 and in two opposing locations on the hollow elongate member of support member 501. Common slots 2101 in at least one hose 420 or at least one tubing 420 may be located closer to second terminal end 422 than to first terminal end 421. Common slots 2101 in the hollow elongate member of support member 501 may be located closer to fifth terminal end 2301 than to sixth terminal end 2302. The common slots 2101 may run substantially parallel with a longitude of at least one hose 420 or at least one tubing 420 and of the hollow elongate member of support member 501. All the common slots 2101 (e.g., four common slots 2101) may be sized to accept passage of portions of threaded bolt/threaded screw 2321 of friction clamp 2322. Portions of threaded bolt/threaded screw 2321 may pass through center hole 2375 of cover 2370, and then through the four common slots 2101, and lastly into threaded hole 2330 (not shown in FIG. 21D, but is shown in FIG. 23E) of recessed channel 2350. See e.g., FIG. 21D.

In combination breathing apparatus and head rest subassembly 2100 common slots 2101 the height adjust means and the forwards-backwards adjust means may be as described in the FIG. 23 series of figures discussion below relating to head rest subassembly 2300. Such height adjust means and forwards-backwards adjust means may comprise, in some embodiments, friction clamp 2322, cover 2370, common slots 2101, the upper bend and/or the upper angle, recessed channel 2350, and channel 2102. Channel 2102 may be a groove in bottom interior surface 217 of the vessel. See e.g., FIG. 21A. A longitude of channel 2102 may be substantially parallel with the forwards-backwards direction, i.e., with a line running center from a center of neck-gasket-accommodator 335 to a center of the back wall (or to a center of recessed channel 2350). A transverse width of channel 2102 may be sized to accommodate an outside diameter of the hollow elongate member of support member 501. Channel 2102 may provide a means for the hollow elongate member of support member 501 to translationally (e.g., slidingly) track in the forward-backwards direction.

When the hollow elongate member of support member 501 may be attached to recessed channel 2350 by threaded bolt 2321 passing through center hole 2375 of cover 2370, and then through common slot 2101, and then finally threaded into threaded hole 2330 (not shown in FIG. 21D, but is shown in FIG. 23E) at a bottom of recessed channel 2350, the hollow elongate member of support member 501 may be slid either forwards or backwards to the desired position of user 9000, with the bottom bend sliding in channel 2102. When friction clamp 2322 may be loose, the hollow elongate member of support member 501 may be adjustable in the forwards-backwards directions. Because of the upper bend (e.g., bend 2315) and/or the upper angle (e.g., angle 2380) in the hollow elongate member of support member 501, adjustments in the forwards-backwards directions may also function to adjust for head height preferences of user 9000. User 9000 may make a single adjustment (e.g. with friction clamp 2322 and sliding) that may result in both a forwards-backwards adjustment and a height adjustment, that may allow different sized heads of various user 9000 s to support and/or rest their respective different sized heads onto various locations of comfortable exterior surface 502, as well as to vary locations of mouth piece 401. When friction clamp 2322 may be tightened, the hollow elongate member of support member 501 may be secured in place in the desired position. In some embodiments, tightening or loosening of friction clamp 2322 may be accomplished by user 9000 turning (rotating) user engagement flange 2323 of friction clamp 2322. In some embodiments, turning user engagement flange 2323 one direction may tighten friction clamp 2322, while turning user engagement flange 2323 an opposite direction may loosen friction clamp 2322.

In some embodiments there may be no common slots 2101; no threaded hole 2330 in a bottom of recessed channel 2350 (see e.g., FIG. 23E for recessed channel 2350 and threaded hole 2330); center hole 2375 may be complimentary inside threaded, cover 2370 may be secured against roof 2340 and/or against recessed channel 2350; and threaded bolt/threaded screw 2321 may be used to press against a top outside of the hollow elongate member of support member 501 closer to fifth terminal end 2301.

FIG. 22A may depict an embodiment of an adjustable breathing apparatus, shown from a perspective view. In some embodiments, an at least one vessel-tube-hose-connector may comprise at least one collar 2201. In FIG. 22A, at least one collar 2201 may replace at least one vessel-tube-hose-connector 430; otherwise this breathing apparatus may comprise mouth piece 401, at least one hose 420 or at least one tubing 420, and at least one collar 2201. Collar 2201 may comprise a central hole with an inside diameter sized to receive an outside diameter of a portion of at least one hose 420 or at least one tube 420. Such sizing of the inside diameter in relation to the outside diameter may permit linear and/or rotational translational movement between collar 2201 and the portion of at least one hose 420 or at least one tube 420 inserted into the central hole.

In some embodiments, when the portion of at least one hose 420 or at least one tube 420 may be inserted into the central hole of collar 2201, the breathing apparatus may be adjustable in a direction of the translational movement. For example, and without limiting the scope of the present invention, this direction of translational movement, may be in a vertical direction (i.e. up-down direction).

In some embodiments, collar 2201 may comprise a means to attach to the vessel (e.g. 200) or a given head rest subassembly. In some embodiments, the means to attach of collar 2201 may comprise a collar-tab 2202. Collar-tab 2202 may protrude from an exterior of collar 2201. See e.g., FIG. 22A. For example, and without limiting the scope of the present invention, in some embodiments, collar-tab 2202 may protrude greater than zero inches and less than two inches from the exterior of collar 2201. In some embodiments, collar-tab 2202 may comprise a terminal flange. Collar-tab 2202 may be received by a side wall tab receiver 2203 located on an interior of at least one side wall 205, e.g. interior wall surface 203. See e.g., FIG. 22A. Side wall tab receiver 2203 may be an indentation, a cavity, or a hole in the side wall 205 (e.g. a hole passing from interior wall surface 203 to exterior wall surface 202). Such a hole may be a port in the vessel. In some embodiments, side wall tab receiver 2203 may be located at or above the liquid (fluid) fill level (e.g. maximum liquid level). Side wall tab receiver 2203 may be sized (via an inside diameter for example) to permit rotational movement between the vessel (e.g. 200) and collar 2201. When collar-tab 2202 may be inserted into side wall tab receiver 2203, the breathing apparatus may be adjustable in a rotational direction with respect to at least one side wall 205 with side wall tab receiver 2203; and also adjustable in the direction of the translational movement (if the portion of at least one hose 420 or at least one tube 420 may be inserted into the central hole of collar 2201). Such adjustments of the breathing apparatus may permit users 9000 of different sizes (and/or ages) to utilize one breathing apparatus which may be adjustable to accommodate differences in the user's 9000 sizes.

In some embodiments, at least one hose 420 or at least one tube 420 may comprise a cap (not depicted in FIG. 22A). The cap may be located at a terminal end (e.g. 422) protruding from collar 2201. The cap may prevent the terminal end (e.g. 422) from slipping through the central hole of collar 2201, once the portion of at least one hose 420 or at least one tube 420 may have been inserted through the central hole. In some embodiments, the cap may comprise a wrapping of tape sufficient to increase the outside diameter of the portion of at least one hose 420 or at least one tube 420 such that the outside diameter is larger than the central hole's inside diameter. In some embodiments, the cap may comprise at least one protrusion (from an exterior of hose 420 or tube 420) which may be large enough to prevent passage through the central hole of collar 2201.

In some embodiments, the cap may be structured so as to not interfere with respiratory gas movement. In some adjustable breathing apparatus embodiments, there may no cap, because in some embodiments, tubes 420 or hoses 420 may be sufficiently long to minimize slip-page out of collar 2201.

FIG. 22B may depict an embodiment of an adjustable breathing apparatus, shown from a close up perspective view. In some embodiments, an at least one vessel-tube-hose-connector may comprise a sleeve 2205. In FIG. 22B, sleeve 2205 may replace at least one vessel-tube-hose-connector 430; otherwise this breathing apparatus may comprise mouth piece 401, at least one hose 420 or at least one tubing 420, and sleeve 2205. Sleeve 2205 may comprise a central hole with an inside diameter sized to receive an outside diameter of a portion of at least one hose 420 or at least one tube 420. Such sizing of the inside diameter in relation to the outside diameter may permit linear and/or rotational translational movement between sleeve 2205 and the portion of at least one hose 420 or at least one tube 420 inserted into the central hole. In some embodiments, sleeve 2205 may be structurally similar to collar 2201, except sleeve 2205 may comprise a longer length.

In some embodiments, when the portion of at least one hose 420 or at least one tube 420 may be inserted into the central hole of sleeve 2205, the breathing apparatus may be adjustable in a direction of the translational movement. For example, and without limiting the scope of the present invention, this direction of translational movement, may be in a vertical direction (i.e. up-down direction). See e.g., FIG. 22B.

In some embodiments, sleeve 2205 may comprise a means to attach to the vessel (e.g. 200) or to a given head rest subassembly. In some embodiments, the means to attach of sleeve 2205 may comprise a sleeve-tab 2206. Sleeve-tab 2206 may protrude from an exterior of sleeve 2205. For example, and without limiting the scope of the present invention, in some embodiments, sleeve-tab 2206 may protrude greater than zero inches and less than two inches from the exterior of sleeve 2205. In some embodiments, sleeve-tab 2206 may comprise a terminal flange. See e.g., FIG. 22B. Sleeve-tab 2206 may be received by a side wall tab receiver 2203 (not depicted clearly in FIG. 22B, instead see FIG. 22A for side wall tab receiver 2203) located on an interior of at least one side wall 205, e.g. interior wall surface 203. In some embodiments, side wall tab receiver 2203 may be located at or above the liquid (fluid) fill level (e.g. maximum liquid level). Side wall tab receiver 2203 may be an indentation, a cavity, or a hole in the side wall 205 (e.g. a hole passing from interior wall surface 203 to exterior wall surface 202). Such a hole may be a port in the vessel. Side wall tab receiver 2203 may be sized (via an inside diameter for example) to permit rotational movement between the vessel (e.g. 200) and collar sleeve 2205. When sleeve-tab 2206 may be inserted into side wall tab receiver 2203, the breathing apparatus may be adjustable in a rotational direction with respect to at least one side wall 205 with side wall tab receiver 2203; and also adjustable in the direction of the translational movement (if the portion of at least one hose 420 or at least one tube 420 may be inserted into the central hole of sleeve 2205). Such adjustments of the breathing apparatus may permit users 9000 of different sizes (and/or ages) to utilize one breathing apparatus which may be adjustable to accommodate differences in the user's 9000 sizes.

In some embodiments, at least one hose 420 or at least one tube 420 may comprise a cap (not depicted in FIG. 22B). The cap may be located at a terminal end (e.g. 422) protruding from sleeve 2205. The cap may prevent the terminal end (e.g. 422) from slipping through the central hole of sleeve 2205, once the portion of at least one hose 420 or at least one tube 420 may have been inserted through the central hole. In some embodiments, the cap may comprise a wrapping of tape sufficient to increase the outside diameter of the portion of at least one hose 420 or at least one tube 420 such that the outside diameter may be larger than the central hole's inside diameter. In some embodiments, the cap may comprise at least one protrusion (from an exterior of hose 420 or tube 420) which may be large enough to prevent passage through the central hole of sleeve 2205.

In some embodiments, the cap may be structured so as to not interfere with respiratory gas movement. In some adjustable breathing apparatus embodiments, there may no cap, because in some embodiments, tubes 420 or hoses 420 may be sufficiently long to minimize slip-page out of sleeve 2205.

FIG. 22C may depict an embodiment of an adjustable breathing apparatus, shown from a close up perspective partial view a side wall tab 2212 in a transparent view inside of channel sleeve 2211 and a comparison view without channel sleeve 2211. In some embodiments, the at least one vessel-tube-hose-connector may comprise a channel sleeve 2211. In FIG. 22C, channel sleeve 2211 may replace at least one vessel-tube-hose-connector 430; otherwise this breathing apparatus may comprise mouth piece 401, at least one hose 420 or at least one tubing 420, and channel sleeve 2211. Channel sleeve 2211 may be connected to a terminal end (e.g., 422) of at least one hose 420 or at least one tube 420. In some embodiments, such a connection may be removable and in other embodiments such a connection may be permanent. In some embodiments, such a connection may be a friction fit between channel sleeve 2211 and the terminal end (e.g., 422) of at least one hose 420 or at least one tube 420.

In some embodiments, channel sleeve 2211 may comprise a central hole in gas communication with an interior of at least one hose 420 or at least one tube 420 connected to the channel sleeve 2211. This connection between channel sleeve 2211 and the terminal end (e.g., 422) of at least one hose 420 or at least one tube 420 may facilitate respiratory gas movement between channel sleeve 2211 and the terminal end (e.g. 422) of at least one hose 420 or at least one tube 420.

In some embodiments, channel sleeve 2211 may comprise a channel 2213 on an exterior surface of channel sleeve 2211 that may face interior wall surface 203. Channel 2213 may run longitudinally along an exterior of channel sleeve 2211. Channel 2213 may be sized to receive a side wall tab 2212. In some embodiments, side wall tab 2212 may be a projection protruding into internal volume 220 of the vessel (e.g. 200) by a proximate distance from a fixed position on at least one side wall 205, e.g. interior wall surface 203. See e.g., FIG. 22C. For example, and without limiting the scope of the present invention, in some embodiments, side wall tab 2212 may protrude greater than zero inches and less than two inches from interior wall surface 203. In some embodiments, side wall tab 2212 may be located at or above the liquid (fluid) fill level (e.g. maximum liquid level). In some embodiments, side wall tab 2212 may comprise a terminal flange 2214.

In some embodiments, when side wall tab 2212 may be held by channel 2213, both linear translational movement, between channel sleeve 2211 and at least one side wall 205 from which side wall tab 2212 may protrude, and rotational movement, between channel sleeve 2211 and a same at least one side wall 205, may be permitted. Such linear translational movement and rotational movement may permit linear translational and rotational adjustments of the breathing apparatus with respect to at least one side wall 205 from which side wall tab 2102 may protrude. Such adjustments of the breathing apparatus may permit users 9000 of different sizes (and/or ages) to utilize one breathing apparatus which may be adjustable to accommodate differences in the user's 9000 sizes.

FIG. 22D may depict an embodiment of an adjustable breathing apparatus, shown from a perspective view, while the breathing apparatus may be in a resting configuration. FIG. 22E may depict the embodiment of FIG. 22D, shown from a perspective view, but while the breathing apparatus may be in an adjustable loaded configuration (i.e., an operational configuration).

In some embodiments, the at least one vessel-tube-hose-connector may comprise two collar hinges 2221. In FIG. 22D and FIG. 22E, two collar hinges 2221 may replace at least one vessel-tube-hose-connector 430; otherwise this breathing apparatus may comprise mouth piece 401, at least one hose 420 or at least one tubing 420, and the two collar hinges 2221. Each collar hinges 2221 may comprise a central hole with an inside diameter sized to receive an outside diameter of a portion of at least one hose 420 or at least one tube 420. When the portion of at least one hose 420 or at least one tube 420 may be inserted into the central hole of collar hinge 2221, linear and/or rotational translational movement may be permitted between collar hinge 2221 and the inserted portion of at least one hose 420 or at least one tube 420. Each collar hinge 2221 may be attached to opposing side walls 205 or opposing rims (e.g. 225) of the vessel (e.g. 200). Each such point of attachment may be a hinged connection permitting swivel movement between collar hinge 2201 and respective side wall 205. See e.g., FIG. 22D and FIG. 22E. Such a hinge may be integral molded hinge.

In some embodiments, the breathing apparatus may comprise two tubes 420 or two hoses 420. Mouthpiece 401 may be disposed between and connected to these comprise two tubes 420 or two hoses 420. In some embodiments, the breathing apparatus may exist in at least one of two configurations, the resting configuration of FIG. 22D and the adjustable loaded configuration of FIG. 22E. In some embodiments, in the resting configuration there may be no user 9000 applied load to the breathing apparatus. In such a configuration, the two tubes 420 or two hoses 420 may remain substantially straight with one portion of each tube 420 or hose 420 passing through one of the central holes of each collar hinge 2201. See e.g., FIG. 22D. “Substantially” as used in the proceeding sentence may mean the two tubes 420 or two hoses 420 may not be geometrically perfectly straight, but rather may have some bend.

In some embodiments, in the adjustable loaded configuration, the user 9000 may be removably holding (engaging) mouthpiece 401 in the user's 9000 mouth and pushing the breathing apparatus down into internal volume 200 of the vessel (e.g. 200). Such pushing may place a load upon the breathing apparatus. Such a load may overcome the resting configuration and cause a shift into the adjustable loaded configuration; which may be a configuration usable by user 9000 for using the face soaking device as intended. In some embodiments, due to inherent flexibility of the two tubes 420 or two hoses 420, the linear translational movement through the central holes of collar hinge 2221, and the swivel movement of collar hinge 2221, the breathing apparatus may be adjustable by user 9000. When user 9000 may be done applying the load to the breathing apparatus, the breathing apparatus may then return to the resting configuration depicted in FIG. 22D, due to inherent elasticity of the two tubes 420 or two hoses 420.

In some embodiments, at least one of the two hoses 420 or two tubes 420 may comprise a cap (not depicted in FIG. 22D nor FIG. 22E). The cap may be located at least one of terminal ends 422. The cap may prevent terminal end 422 from slipping through the central hole of collar hinge 2221, once the portion of the hose 420 or the tube 420 may have been inserted through the central hole. In some embodiments, the cap may comprise a wrapping of tape sufficient to increase the outside diameter of the portion of at least one hose 420 or at least one tube 420 such that the outside diameter may be larger than the central hole's inside diameter. In some embodiments, the cap may comprise at least one protrusion (from an exterior of hose 420 or tube 420) which may be large enough to prevent passage through the central hole of collar hinge 2221.

In some embodiments, the cap may be structured so as to not interfere with respiratory gas movement. In some adjustable breathing apparatus embodiments, there may no cap, because in some embodiments, tubes 420 or hoses 420 may be sufficiently long to minimize slip-page out of collar hinge 2221.

In some embodiments, a FIG. 16 series of figures, a FIG. 17 series of figures, a FIG. 18 series of figures, and a FIG. 19 series of figures may all address and focus on various nose-clip embodiments. Such nose-clips may be intended to be used in conjunction with using various face soaking device embodiments. In some embodiments, a system may comprise a given face soaking device along with a given nose-clip embodiment. Such nose-clips may facilitate use with various breathing apparatus embodiments. For some users 9000, they may desire use of a nose-clip to close their nostrils when otherwise using their mouth to breathe by using a given breathing apparatus embodiment.

In some embodiments of using various face soaking device embodiments (e.g., face soaking device 100), user 9000 may also use a nose-clip 1600, a nose-clip 1700, a nose-clip 1800, a nose-clip 1900, nose-plugs, and/or any other device suitable for closing (e.g. sealing and/or shutting) nostrils off from liquid 101. Closing off the nostrils of user 9000 may facilitate ease of breathing when face 9010 may be immersed in liquid 101. In some embodiments, a system (kit) for soaking face 9010 of user 9000 may comprise face soaking device 100 and at least one of: nose-clip 1600, nose-clip 1700, nose-clip 1800, nose-clip 1900, nose-plugs, and/or any other device suitable for removably closing nostrils off from liquid 101.

In some embodiments, such nose-clip(s) may be constructed from at least one wire that may bend without breaking, such that the at least one wire may be bent into a shape which removably clamps the nostrils shut. When bent to clamp the nostrils shut, the at least one wire may be sufficiently strong to resist forces exerted by the nostrils on the wire.

FIG. 16A may depict an exemplary embodiment of nose-clip 1600, comprising tight coils 1609, shown from a top perspective view. FIG. 16B may depict nose-clip 1600, shown from a bottom perspective view. FIG. 16C may depict nose-clip 1600, shown from a front view. FIG. 16D may depict nose-clip 1600, shown from a side view. FIG. 16E may depict nose-clip 1600, shown from a back view. FIG. 16F may depict nose-clip 1600, shown from a top view. FIG. 16G may depict nose-clip 1600, shown from a bottom view.

In some embodiments, nose-clip 1600 may comprise a wire that may be at least one elongate member 1602 with two disposed opposite terminal ends 1603. In some embodiments, the at least one wire may be bent generally into a “U” shape with a central bend region 1605 forming a major radius 1606 of the “U” shape. See e.g., FIG. 16A. When in use, each terminal end 1603 and/or each terminal end region may be brought towards each other pinching the nostrils shut between to the two terminal ends 1603 and/or the two terminal end regions. When in use, the central bend region 1605 may be either over a bridge of the nose or disposed under the nostrils, i.e. closer to a mouth than to the bridge. To remove such a wire, the two terminal ends 1603 and/or the two terminal end regions may be bent away from each other a distance sufficient to permit the nostrils to open and for the wire to be removed from the nose.

In some embodiments, each terminal end 1603 or each terminal end region may form a terminating structure 1607. See e.g., FIG. 16A. In some embodiments, terminating structure 1607 may comprise one or more of: a series of tight coils 1609 (see e.g., FIG. 16A through FIG. 16G), a series of loose coils 1710 (see e.g., FIG. 17A through FIG. 17G), an ovoid structure, a spherical structure 1811 (see e.g., FIG. 18A through FIG. 18F), a disk structure, a rod structure, and/or the like. Such terminating structures may form a pad 1608. See e.g., FIG. 16C. Pad 1608 may provide additional surface area to exert against each nostril.

In some embodiments, each terminating structure 1607 may be formed by bending the terminal ends 1603 into the terminating structure 1607, e.g. with the series of tight coils 1609 (see e.g., FIG. 13A through FIG. 13G) and/or with the series of loose coils 1710 (see e.g., FIG. 17A through FIG. 17G). A curvature associated with major radius 1606 may be more gentle (less curved) than curvatures associated with tight coils 1609 and/or with loose coils 1710. That is, curvatures associated with tight coils 1609 and/or with loose coils 1710 may be greater (bend sharper) than the curvature associated with major radius 1606. The curvature associated with tight coils 1609 may be greater (bend sharper) than the curvature associated with loose coils 1710 (see e.g., FIG. 17A for loose coils 1710).

In some embodiments, each terminating structure 1607 may be constructed of a same material, such as at least one wire. In some embodiments, each terminating structure 1607 may be constructed of a material different than that of the at least one wire.

In some embodiments, the at least one wire may be a metal wire. In some embodiments, the at least one wire may be a solid metal wire. In some embodiments, the metal may be one or more of copper, aluminum, steel, stainless steel, brass, various alloys, and the like.

In some embodiments, the at least one metal wire and/or the at least one elongate member 1602 may be coated with a polymer. See e.g., nose-clip 1900 embodiments of FIG. 19A through FIG. 19G. This polymer coating may waterproof the metal wire and/or the at least one elongate member 1602. The polymer may provide durability to the wire, e.g. by minimizing corrosion. The polymer may also promote comfort to user 9000 when being worn. The polymer may also comprise various colorants so the polymer when cured appears in a variety of colors. The polymer may be a plastic and/or an elastomer (e.g. silicone, rubber, etc.). For example, and without limiting the scope of the present invention, the plastic may be a plastisol type of PVC suspension wherein the wire may be dipped into a liquid plastisol and then cured into a plastic covering of the wire. In a similar fashion, the wire may be powder coated with the polymer (plastic).

FIG. 17A through FIG. 17G may depict nose-clip 1700 with loose coils 1710. Aside from loose coils 1710, nose-clip 1700 may be substantially similar to nose-clip 1600. FIG. 17A may depict an exemplary embodiment of nose-clip 1700, comprising loose coils 1710, shown from a top perspective view. FIG. 17B may depict nose-clip 1700, shown from a bottom perspective view. FIG. 17C may depict nose-clip 1700, shown from a front view. FIG. 17D may depict nose-clip 1700, shown from a side view. FIG. 17E may depict nose-clip 1700, shown from a back view. FIG. 17F may depict nose-clip 1700, shown from a top view. FIG. 17G may depict nose-clip 1700, shown from a bottom view.

FIG. 18A through FIG. 18F may depict nose-clip 1800 with spherical structure 1811. In some embodiments, terminating structure 1607 of nose-clip 1800 may comprise spherical structure 1811; otherwise nose-clip 1800 may be substantially similar to nose-clip 1600. FIG. 18A may depict an exemplary embodiment of nose-clip 1800, comprising a pair of spherical terminating structures 1811, shown from a top perspective view. FIG. 18B may depict nose-clip 1800, shown from a bottom perspective view. FIG. 18C may depict nose-clip 1800, shown from a front view. FIG. 18D may depict nose-clip 1800, shown from a side view. FIG. 18E may depict nose-clip 1800, shown from a back view. FIG. 18F may depict nose-clip 1800, shown from a top view.

FIG. 19A may depict an exemplary embodiment of nose-clip 1900, wherein nose-clip 1900 may be coated with a polymer, shown from a top perspective view. FIG. 19B may depict nose-clip 1900, shown from a bottom perspective view. FIG. 19C may depict nose-clip 1900, shown from a front view. FIG. 19D may depict nose-clip 1900, shown from a side view.

In some embodiments, nose-clip 1900 may be substantially similar to nose-clip 1600, except elongate member 1602 of nose-clip 1900 may be coated with the polymer. In some embodiments, when the at least one wire may be coated with the polymer, such that surface area of pad 1608 may be increased. See e.g., FIG. 19A. For example, and without limiting the scope of the present invention, when the terminal ends 1603 may be bent into the series of tight coils 1609, that series of tight coils 1609 once coated with the polymer may appear as a disc like pad 1608, with no air gaps remaining between tight coils. See e.g., FIG. 19A.

In some embodiments, the at least one solid metal (e.g., of nose-clip 1600, nose-clip 1700, nose-clip 1800, and/or nose-clip 1900) wire may be 10 gauge to 12 gauge in diameter. In some embodiments, the at least one solid metal (e.g., of nose-clip 1600, nose-clip 1700, nose-clip 1800, and/or nose-clip 1900) wire may be 8 gauge to 16 gauge in diameter. Testing may have determined that copper wire diameters of smaller than 12 gauge, for example 14 gauge, may not have sufficient strength to effectively clamp some nostrils shut. Testing may have determined that copper wire diameters greater than 10 gauge may be difficult for some users (e.g. children and/or elderly users) to bend the wire such that the wire may clamp the nostrils shut.

In some embodiments, the at least one elongate member 1602 may be a plurality of elongate members. For example, and without limiting the scope of the present invention, in some embodiments there may be two or three elongate members, wherein each elongate member may be a metal wire, such the plurality of metal wires, may together be bent into the “U” shape. Such a plurality of metals wires may be generally parallel with each other. Such a plurality of metal wires may be wrapped helically around each other. Such a plurality of metal wires may be twisted around each other. Such a plurality of metal wires may be braided with each other. When a plurality of metal wires may be used, smaller diameters (higher gauges) of metal wire may be used.

In some embodiments, any such nose-clip as noted above may also comprise a leash (i.e., tether), wherein the leash may removably tether the nose-clip to another object of vessel 200 or some subassembly of a given face soaking device (e.g., face soaking device 100), such that the nose-clip may be on hand when user 9000 may want to use the nose-clip. Such a leash may minimize loss of the nose-clip. For example, and without limiting the scope of the present invention, the leash may removably tether the nose-clip to breathing apparatus 400. For example, and without limiting the scope of the present invention, the leash may removably tether the nose-clip to rim 225.

In some embodiments, angle 2380 may be measured from less than 180 degrees and more than 90 degrees between the lower surface of sixth terminal end 2302 and the lower surface of fifth terminal end 2301.

Alternatively, a corresponding angle may be measured of less than 90 degrees, wherein the corresponding angle may be measured as between upper surface 2311 proximate to sixth terminal end 2302 and a plane which may be collinear with a portion of upper surface 2311 proximate to fifth terminal end 2301. For example, and without limiting the scope of the present invention, if the corresponding angle may be 60 degrees, then angle 1580 may be 120 degrees.

In some embodiments, the at least the portion of the forwards-backwards adjust means may comprise slot 2320 located in the flat rod (or in the elongate member of support member 501). In some embodiments, not only may slot 2320 be an element of the forwards-backwards adjust means, but slot 2320 may also be a structural element of support member 501. In some embodiments, slot 2320 may run parallel with a longitude of the flat rod (or in the elongate member of support member 501). In some embodiments, slot 2320 may be proximate to fifth terminal end 2301, i.e. slot 2320 may be closer fifth terminal end 2301 than to sixth terminal end 2302. See e.g., FIG. 23E. In some embodiments (not depicted), slot 2320 may run substantially along a length of support member 501. In some embodiments, the forwards-backwards adjust means may also comprise friction clamp 2322. In some embodiments, a portion of friction clamp 2322 may be configured to pass through an opening of slot 2320 to attach support member 501 to the vessel. See e.g., FIG. 23A and FIG. 23E.

In some embodiments, friction clamp 2322 may comprise a threaded bolt 2321 (or threaded screw 2321) attached to a user engagement flange 2323. In some embodiments, threaded bolt 2321 (or threaded screw 2321) and user engagement flange 2323 may be integral to each other. In some embodiments, threaded bolt 2321 (or threaded screw 2321) may comprise outside threading. In some embodiments, threaded bolt 2321 (or threaded screw 2321) or portions thereof, may be configured to pass through the opening of slot 2320. In some embodiments, user engagement flange 2323 may be configured to be gripped by user 9000. In some embodiments, user engagement flange 2323 may be configured to be rotated by user 9000 gripping user engagement flange 2323, which may then rotate threaded bolt 2321 (or threaded screw 2321). In some embodiments, user engagement flange 2323 may comprise a pair of wings (e.g., as in a wing bolt), and/or undulations around a circumference of the flange of user engagement flange 2323, wherein the undulations may facilitate gripping.

In some embodiments, the forwards-backwards adjust means may further comprise a location of attachment to the vessel (e.g., vessel 200). In some embodiments, the location of attachment to the vessel may comprise a threaded hole 2330 into the vessel (e.g., vessel 200). In some embodiments, threaded hole 2330 may comprise complimentary inside threading that may be complimentary to the outside threading of threaded bolt 2321. See e.g., FIG. 23E. In some embodiments, threaded hole 2330 may be configured to receive threaded bolt 2321, such that threaded bolt 2321 may be screwed into and out of threaded hole 2330.

In some embodiments, the location of attachment to the vessel may be on a roof 2340 of rim 225 of at least one side wall 205 of the vessel (e.g., vessel 200). See e.g., FIG. 23E. In some embodiments, roof 2340 may be an upper exterior surface of rim 225 or portion thereof. In some embodiments, roof 2340 may be a substantially horizontal flat structure in reference to bottom interior surface 217 of internal volume 220 of vessel 200. In some embodiments, roof 2340 may comprise a slope.

In some embodiments, roof 2340 may be a roof to mechanical compartment 251. See e.g., FIG. 23E. In some embodiments, mechanical compartment 251 may be a compartment disposed between exterior wall surface 202 and interior wall surface 203. In some embodiments, mechanical compartment 251 may be a compartment disposed between vessel lining 200 a and vessel cover 200 b. In some exemplary embodiments, mechanical compartment 251 may be disposed opposite of neck-gasket-accommodator 335, disposed between vessel lining 200 a and vessel cover 200 b. In some embodiments, mechanical compartment 251 may be formed between exterior portions of second side wall 207 of vessel cover 200 b and interior portions of second side wall 207 of vessel lining 200 a. See e.g., FIG. 1B and FIG. 5G. In some embodiments, this mechanical compartment 251 may house at least some portions of electronics (e.g., controller 1100 and compressor 1110) and some portions of airline tubing 819 of face soaking device 100. In some embodiments, mechanical compartment 251 may comprise an access door located in exterior wall surface 202 (this access door is not depicted).

In some embodiments, roof 2340 may comprise recessed channel 2350. See e.g., FIG. 23E. In some embodiments, recessed channel 2350 may be configured to receive a portion of the support member 501 which may include slot 2320. In some embodiments, recessed channel 2350 may comprise a transverse width configured to fit a transverse width of support member 501, e.g., a transverse width of support member 501 proximate to fifth terminal end 2301. In some embodiments, recessed channel 2350 may include threaded hole 2330. See e.g., FIG. 23E. In some embodiments, recessed channel 2350 may be molded integrally with roof 2340. In some embodiments, a longitude of recessed channel 2350 may be parallel with a line running straight center from neck-gasket-accommodator 335 to at least one wall 201 (e.g., at least one side wall 205) directly opposite of neck-gasket-accommodator 335. In some embodiments, when support member 501 may be attached to recessed channel 2350 by threaded bolt 2321 passing through slot 2320 and into threaded hole 2330, support member 501 may slide either forwards or backwards within recessed channel 2350 to a desired position for user 9000. When friction clamp 2322 may be loose, support member 501 may be adjustable in the forwards-backwards directions. Because of bend 2315 and/or angle 2380 in support member 501, adjustments in the forwards-backwards directions may also function to adjust for head height preferences of user 9000. User 9000 may make a single adjustment (e.g., using slot 2320 and friction clamp 2322) that may result in both a forwards-backwards adjustment and a height adjustment; that may allow different sized heads of various user 9000 s to support and/or rest their respective different sized heads onto various locations of upper surface 2311 and/or comfortable exterior surface 502. When friction clamp 2322 may be tightened, support member 501 may be secured in place in a particular desired position for a given user 9000. In some embodiments, tightening or loosening of friction clamp 2322 may be accomplished by user 9000 turning (rotating) user engagement flange 2323. In some embodiments, turning user engagement flange 2323 clockwise may tighten friction clamp 2322, while turning user engagement flange 2323 counterclockwise may loosen friction clamp 2322. In some embodiments, turning user engagement flange 2323 counterclockwise may tighten friction clamp 2322, while turning user engagement flange 2323 clockwise may loosen friction clamp 2322.

In some embodiments, the forwards-backwards adjust means may further comprise cover 2370. See e.g., FIG. 23E and FIG. 23A. When assembled, cover 2370 may be disposed between friction clamp 2322 and support member 501. Cover 2370 may cover slot 2320. Cover 2370 may fixedly attach to recessed channel 2350. In some embodiments, cover 2370 may also be configured to fit over recessed channel 2350. Cover 2370 may comprise a center hole 2375 large enough to permit passage of threaded bolt 2321. Center hole 2375 may be threaded (e.g., inside threaded) in some embodiments to accept threaded bolt 2321. Center hole 2375 may not be threaded in some embodiments, but may accept threaded bolt 2321 passing through center hole 2375 by center hole 2375 having an inside diameter larger than an outside diameter of threaded bolt 2321. In some embodiments, tightening friction clamp 2322, may cause cover 2370 to push against support member 501 to secure support member 501 into a given desired position for user 9000.

In some embodiments, roof 2340 may comprise a sleeve. This sleeve may be located where recessed channel 2350 may have otherwise been located in roof 2340. This sleeve may function as recessed channel 2350 and cover 2370 may function together. This sleeve may combine both the structures and the functionality of recessed channel 2350 and cover 2370. This sleeve may be configured to circumscribe a portion of support member 501, which may include slot 2320. This sleeve may comprise threaded hole 2330 and an opposing upper hole in the sleeve. In some embodiments, threaded hole 2330 and the opposing upper hole may be collinear. Fifth terminal end 2301 and portions of support member 501, with slot 2320, may pass slidingly into a main cavity of this sleeve. A longitude of this main cavity may be perpendicular to a collinear line passing through threaded hole 2330 and the opposing upper hole.

In some embodiments, this sleeve may be a single molded part that may be attached to roof 2340 or attached to recessed channel 2350. In some embodiments, this sleeve may comprise recessed channel 2350 and cover 2370, wherein the opposing upper hole and center hole 2375 may be collinear. In some embodiments, this sleeve may be molded integrally with vessel 200, e.g., an as an integral component of roof 2340.

In some embodiments, a longitude of this sleeve may be parallel with a line running straight center from neck-gasket-accommodator 335 to at least one wall 201 (e.g., at least one side wall 205) directly opposite of neck-gasket-accommodator 335. When support member 501 may be attached to this sleeve by threaded bolt 2321 passing through the opposing upper hole, and then into slot 2320, and then finally threaded into threaded hole 2330, support member 501 may be slid either forwards or backwards to the desired position of user 9000. When friction clamp 2322 may be loose, support member 501 may be adjustable in the forwards-backwards directions. Because of bend 2315 and/or angle 2380 in support member 501, adjustments in the forwards-backwards directions may also function to adjust for head height preferences of user 9000. User 9000 may make a single adjustment (e.g., using slot 2320 and friction clamp 2322) that may result in both a forwards-backwards adjustment and a height adjustment, that may allow different sized heads of various user 9000 s to support and/or rest their respective different sized heads onto various locations of upper surface 2311 and/or comfortable exterior surface 502. When friction clamp 2322 may be tightened, support member 501 may be secured in place in the desired position. In some embodiments, the opposing upper hole may be large enough to permit frictional pressure to be applied from friction clamp 2322 to support member 501. In some embodiments, tightening or loosening of friction clamp 2322 may be accomplished by user 9000 turning (rotating) user engagement flange 2323. In some embodiments, turning user engagement flange 2323 one direction may tighten friction clamp 2322, while turning user engagement flange 2323 an opposite direction may loosen friction clamp 2322.

Because of the angle of bend 2315, when the head of user 9000 may be removably resting upon upper surface 2311 (and/or comfortable exterior surface 502), it may be possible for the face soaking device to slide away from user 9000. That is, a weight of the head of user 9000 may result in part in a force f_(x) directed horizontally away from user 9000, which if sufficient to overcome a frictional force and a weight of the face soaking device (including liquid 101), the face soaking device may slide away from user 9000. See e.g., FIG. 23F.

A head rest subassembly 2400 embodiment, depicted in a FIG. 24 series of figures, may provide a solution to this potential sliding problem of head rest subassembly 2300. In some embodiments, head rest subassembly 2400 may replace head rest subassembly 2300. See e.g., FIG. 24A, FIG. 24B, FIG. 24C, and FIG. 24D.

FIG. 24A may depict an assembled overall perspective view of a face soaking device with head rest subassembly 2400. FIG. 24B may depict head rest subassembly 2400, but with a portion of head rest subassembly 2400 tilted upwards. FIG. 24C may depict the head rest subassembly 2400, but from a top view. FIG. 24D may depict the head rest subassembly 2400, but showing a transparent view within mechanical compartment 251.

In some embodiments of face soaking devices the face soaking device may comprise head rest subassembly 2400. In some embodiments, head rest subassembly 2400 may comprise: support member 501 and at least one longitudinal-support 2420. In some embodiments support member 501 may comprise a transverse-head-support-member 2410. In some embodiments, head rest subassembly 2400 may comprise: transverse-head-support-member 2410 and at least one longitudinal-support 2420. See e.g., FIG. 24A. In some embodiments, transverse-head-support-member 2410 may be rigid to semi-rigid. In some embodiments, transverse-head-support-member 2410 may be made from round bar. In some embodiments, at least one longitudinal-support 2420 may be rigid to semi-rigid.

In some embodiments, transverse-head-support-member 2410 may be for supporting at least the portion of the head of user 9000. In some embodiments, transverse-head-support-member 2410 may be substantially perpendicular with respect to a line running from a front to a back of the face soaking device. The front of a given face soaking device may be closer to the vessel neck gasket (e.g., vessel neck gasket 340) than the back and the back may be disposed opposite of the front.

In some embodiments, at least one longitudinal-support 2420 may be coupled to the transverse-head-support-member 2410. See e.g., FIG. 24A. In some embodiments, at least one longitudinal-support 2420 may provide structural support to transverse-head-support-member 2410. In some embodiments, at least one longitudinal-support 2420 may carry loads applied to transverse-head-support-member 2410. In some embodiments, at least one longitudinal-support 2420 may comprise two opposing ends, a first-end 2421 and a second-end 2422, where second-end 2422 may be in physical contact with the at least one wall 201 or may be passing into at least one wall 201. In some embodiments, this second-end 2422 may be anchored in mechanical compartment 251. See FIG. 24D for second-end 2422. In some embodiments, at least one wall 201 (e.g., a back wall) may comprise a vertical slot 2451 that may provide at least one longitudinal-support 2420 with access to mechanical compartment 251. See e.g., FIG. 24A. In some embodiments, head rest subassembly 2400 may be substantially, but not entirely, located within internal volume 220 of a given face soaking device embodiment. For example and without limiting the scope of the present invention, knob 2443 may be located exteriorly of internal volume 220. Or during maintenance and/or adjustments, portions of head rest subassembly 2400 may be tilted out (and/or removed) of internal volume 220. See e.g., FIG. 24B. And second-end 2422 of at least one longitudinal-support 2420 may be located in mechanical compartment 251 (see FIG. 24D).

Turning back to discussing FIG. 24A, in some embodiments, transverse-head-support-member 2410 may be a curved elongate member. In some embodiments, a curve of the curved elongate member of transverse-head-support-member 2410 may curve into internal volume 220 of the vessel of the face soaking device. In some embodiments, transverse-head-support-member 2410 may comprise at least one comfortable exterior surface 502. In some embodiments, at least one comfortable exterior surface 502 may comprise one or more of a cushion or a soft material. In some embodiments, the cushion or the soft material is disposed on an upper surface of the at least one comfortable exterior surface 502 to provide padding to the portion of the head of user 9000. See e.g., FIG. 24A.

In some embodiments, at least one longitudinal-support 2420 may be substantially parallel with the line running from the front to the back of the face soaking device. In some embodiments, at least one longitudinal-support 2420 may be substantially an elongate member. In some embodiments, at least one longitudinal-support 2420 may be substantially an “L” shaped elongate member. In some embodiments, a region proximal to a bend that forms an “L” in the at least one longitudinal-support 2420 may be substantially flat to operate as a spring hinge. In some embodiments, second-end 2422 (of at least one longitudinal-support 2420) may be received in a cavity 2461, in mechanical compartment 251, or cavity 2461 in mechanical compartment 251. See FIG. 24D. In some embodiments, this cavity 2461 may be located in mechanical compartment 251 (or in physical contact with mechanical compartment 251 or proximal to mechanical compartment 251, but closer to the back than to the front) of the vessel of the face soaking device. In some embodiments, a longitude of this cavity 2461 may be oriented substantially vertical with respect to a ground (substrate) upon which the face soaking device may be located on. In some embodiments, this longitude of this cavity 2461 may be oriented substantially vertical with respect to a surface of at least one base 215 (i.e., substantially perpendicular with respect to the surface of at least one base 215). In some embodiments, a size (diameter and longitude) of this cavity 2461 may be sized to form a frictional press fit with second-end 2422 (at least one longitudinal-support 2420) or with a region of at least one longitudinal-support 2420 within a proximate distance of second-end 2422 (at least one longitudinal-support 2420). See e.g., FIG. 24D. In some embodiments, this proximate distance may be within: five inches, six inches, seven inches, eight inches, and the like.

In some embodiments, at least one longitudinal-support 2420 may comprise two longitudinal-supports 2420, a first longitudinal-support 2420 and a second longitudinal-support 2420. See e.g., FIG. 24A. In such embodiments, transverse-head-support-member 2410 may comprise opposing ends, wherein each opposing end may be (slidingly) coupled to a portion of each of the two longitudinal-supports 2420. In some embodiments, the two longitudinal-supports 2420 may be substantially parallel with each other. Note in embodiments with two longitudinal-supports 2420 there may be two couplings 2430, two vertical slots 2451, and two cavities housing the second-end of at least one longitudinal-support 2420. See e.g., FIG. 24A.

In some embodiments, head rest subassembly 2400 may comprise a forwards-backwards adjust means for removable setting of a location of the transverse-head-support-member 2410 along a longitude of at least one longitudinal-support 2420. In some embodiments, this forward-backwards adjust means may comprises a coupling 2430 that may connect at least one longitudinal-support 2420 to transverse-head-support-member 2410. See e.g., FIG. 24A. In some embodiments, an end of transverse-head-support-member 2410 may be attached to coupling 2430. In some embodiments, this point of attachment of the ends of trans-verse-head-support-member 2410 to coupling 2430, may be a freely rotatable hinge, to permit free swing motion of transverse-head-support-member 2410 with respect to coupling 2430 (and at least one longitudinal-support 2420). In some embodiments, coupling 2430 may comprise a receiving-hole 2431 for receiving a portion of the at least one longitudinal-support 2420. In some embodiments, receiving-hole 2431 may be sized (e.g., diameter) to permit sliding of coupling 2430 along the longitude of the at least one longitudinal-support 2420. In some embodiments, receiving-hole 2431 may be sized to permit frictional sliding of coupling 2430 along the longitude of the at least one longitudinal-support 2420. In some embodiments, coupling 2430 may comprise a set screw 2435 for setting the location by applying removable friction to the portion of at least one longitudinal-support 2420. Tightening set screw 2435 may prevent or minimize sliding of coupling 2430 along the longitude of at least one longitudinal-support 2420. See e.g., FIG. 24A.

In some embodiments, coupling 2430 may comprise a spring loaded set pin (not depicted) for setting the location by applying removable friction to the portion of at least one longitudinal-support 2420. Such a spring loaded set pin may be an alternative to set screw 2435. Such a spring loaded set pin may have two operational states, a resting state and pressed state. In the resting state the spring may cause spring loaded set pin to exert pressure against the portion of at least one longitudinal-support 2420. In the pressed state, an exterior of the spring loaded set pin may be pushed by user 9000, compressing the spring and releasing pressure against the portion of at least one longitudinal-support 2420. In some embodiments, at least one longitudinal-support 2420 may comprise a plurality of holes (not depicted), spaced at various intervals, for removably receiving of the pin of the spring loaded set pin when in the resting state. Note, the spring loaded set pin may not be depicted in the FIG. 24 series drawing (figures).

In some embodiments, head rest subassembly 2400 may comprise a height adjust means for removable setting of a vertical location of transverse-head-support-member 2410 with respect to the ground (i.e., the substrate) that the face soaking device may be located upon. In some embodiments, head rest subassembly 2400 may comprise the height adjust means for removable setting of the vertical location of transverse-head-support-member 2410 with respect to the surface of at least one base 215 (i.e., bottom interior surface 217).

In some embodiments, the height adjust means may comprise a set-bolt 2441 (as part of knob 2443) and a head-rest-brake 2445. See FIG. 24D. In some embodiments, this head-rest-brake 2445 may be located in mechanical compartment 251. In some embodiments, this head-rest-brake 2445 may be a flat bar, with a longitude parallel with a transverse width of the vessel. In some embodiments, this head-rest-brake 2445 may comprise a central threaded hole (inside threaded) sized to receive a threaded portion (outside threading) of the set-bolt of knob 2443. In some embodiments, this head-rest-brake 2445 may be comprise an upper surface 2446 to support a region of at least one longitudinal-support 2420 disposed away from first-end 2421. In some embodiments, turning knob 2443 may raise or lower, depending upon a direction of rotation, this head-rest-brake 2445 in a vertical direction with respect to the surface of at least one base 215; which in turn may raise or lower, at least one longitudinal-support 2420, since portions of at least one longitudinal-support 2420 may resting on ends of this head-rest-brake 2445. See e.g., FIG. 24D.

In some embodiments, this set-bolt 2441 may comprise knob 2443 located outside of mechanical compartment 251 exteriorly of roof 2340. In some embodiments, some of threaded portion 2442 of this set-bolt may pass through the center hole of roof 2340, such that knob 2443 remains exterior to mechanical compartment 251. See FIG. 24D. In some embodiments, knob 2443 may comprise perimeter geometry that provides friction when gripped by user 9000. For example, and without limiting the scope of the present invention this perimeter geometry may comprise finger indentations, alternating ridges, undulations, and the like. This set-bolt 2441 may be substantially similar to the structure of friction clamp 2322.

A FIG. 25 series of figures may comprise FIG. 25A through FIG. 25H. These FIG. 25 series of figures may depict various head rest subassembly embodiments (e.g., 2500, 2540, 2550, and 2560).

In some embodiments, at least one strut 2511 may be horizontal or substantially horizontal, when installed in internal volume 220.

In some embodiments, fourth terminal end 2513 of a given strut 2511 may connect to exterior wall surface 202, to interior wall surface 203, and/or to bottom interior surface 217. For example, and without limiting the scope of the present invention, fourth terminal end 2513 may connect to interior surface of at least one base 215 (bottom interior surface 217) or to one of interior side wall surfaces 203. In some embodiments, where fourth terminal end 2513 may connect to one of interior side wall surfaces 203, at least one strut 2511 may be horizontal or substantially horizontal.

For example, and without limiting the scope of the present invention, the fourth terminal end 2513 may connect to at least one exterior side wall(s) 202.

In some embodiments, a point of connection of fourth terminal end 2513 and of wall 201 of vessel 200, whether to interior wall surface 203 or to exterior wall surface 202, may be via a strut attachment means 2530.

In some embodiments, head rest subassembly 2500 may comprise strut attachment means 2530. Strut attachment means 2530 may be configured to connect fourth terminal end 2513 to at least one wall 201 of vessel 200. In some embodiments, strut attachment means 2530 may comprise wing bolt 2531 and an inside threaded hole through at least one strut 2511 for accepting this wing bolt 2531. See e.g., FIG. 25B and FIG. 25C.

In some embodiments, strut attachment means 2530 may be configured to connect fourth terminal end 2513 to at least one base 215 of vessel 200.

In some embodiments strut attachment means 2530 may comprise a track and complimentary flange system. For example, the track may be located on exterior wall surface 202 or interior wall surface 203 and the flange may be at fourth terminal end 2513. The flange may be received and captured by the track and slide along a groove of the track. See FIG. 26A and FIG. 26E for track and flange embodiments.

In some embodiments strut attachment means 2530 may comprise a pivotable locking means 2520. In some embodiments, wing bolt 2531 may be the same component as the wing bolt of friction clamp 2522. See FIG. 25F through FIG. 25H discussed below after the FIG. 25D discussion.

FIG. 25D may depict an alternative embodiment of a head rest subassembly 2540, shown from an exploded top perspective view. A support member 501 may be adjusted vertically, wherein the support member 501 may be a component of head rest subassembly 2540.

In some embodiments, head rest subassembly 2540 may comprise support member 501 and comfortable exterior surface 502 in communication with support member 501. In some embodiments, head rest subassembly 2540 may comprise a height adjust means. In some embodiments, the height adjust means may comprise at least one strut 2511. Each strut 2511 may comprise third terminal end 2512 and fourth terminal end 2513 disposed opposite of third terminal end 2512.

Here in FIG. 25D with head rest subassembly 2540, support member 501 (or the strap) may be adjusted vertically by use of height adjustment slots 2514.

See e.g., FIG. 7L.

In some embodiments, where there may be one bushing 703 per one element 702, installment of at least one heating element 701 may occur from inside internal volume 220 (e.g., when the overall shape may be the linear shape with one bend), e.g. by passing at least a portion of connection bushing 704 into bushing hole 708 from internal volume 220 side. See e.g., FIG. 7M and FIG. 7N.

In some embodiments, where there may be one bushing 703 per one element 702, installment of at least one heating element 701 may occur from outside internal volume 220 (e.g., from mechanical compartment 251), e.g. by passing element 702 into bushing hole 708 and then into internal volume 220. This installment embodiment is not depicted in the FIG. 7 series of figures.

In some embodiments, at least one heating element 701 may comprise low watt density (LWD) consumption and/or high watt density (HWD) consumption in other embodiments. In some embodiments, LWD may be about 55 watts per square inch or less; and HWD may be greater than 55 watts per square inch. Whereas, in some embodiments, LWD may be about 60 watts per square inch or less; and HWD may be greater than 60 watts per square inch. (“About” as used in this paragraph may mean plus or minus two watts in some embodiments.) The more element 702 surface area, the lower the wattage per square inch needed to heat liquid 101, and the less concern for plastic parts melting and/or deforming. Increasing such surface area may accomplished by using longer (lengthwise) element(s) 702 and/or by coiling element(s) 702. Also, the lower the wattage per square inch of at least one heating elements 701, the longer (temporally) at least one heating elements 701 may last.

In some embodiments, element receiving channel 711 may be bounded on three sides by three different at least one walls 201 (or three different at least one side wall 205). In some embodiments, element receiving channel 711 may be bounded on one side by LED-housing 950. In some embodiments, element receiving channel 711 may be bounded on four sides as follows: by two sides by two different, but adjacent, at least one walls 201 (or three different at least one side wall 205), bounded one side by bushing hole 708, and bounded the final side by LED-housing 950. See e.g., FIG. 7H.

FIG. 7A may depict an assembled heater subassembly 700, while in communication (e.g., attached) with the vessel (e.g., vessel 200), shown from a top perspective view, but with the breathing apparatus (e.g., breathing apparatus 400), the head rest subassembly (e.g., head rest subassembly 500), and portions of the gas diffuser (e.g., gas diffuser 800) removed. However, when heater subassembly 700 may be assembled and attached to the vessel (e.g., vessel 200), from this top perspective view, only aspects of a shield 715 may be viewable. Shield 715 may be a component of heater subassembly 700. That is, in some embodiments, heater subassembly 700 may comprise shield 715.

FIG. 7C through FIG. 7G may focus on depicting shield 715 from different views. FIG. 7C may depict shield 715, shown from a top view. FIG. 7D may depict shield 715, shown from a bottom view. FIG. 7E may depict shield 715, shown from a front view. FIG. 7F may depict shield 715, shown from a back view. FIG. 7G may depict shield 715, shown from a longitudinal side view.

Shield 715 may be configured to protect user 9000 from physically touching element 702 and/or to protect user 9000 from physically touching a component of at least one heating element 701 which may be hot to touch. Shield 715 may be configured to minimize objects from touching element 702 and/or configured to minimize objects from touching a component of at least one heating element 701 which may be hot. Such objects may be similar sized as a diameter of a human pinky finger. In some embodiments, shield 715 may be substantially constructed from a heat resistant thermoformed plastic. For example, and without limiting the scope of the present invention, shield 715 may be constructed from chlorinated polyvinyl chloride (CPVC) and/or the like. Such materials of construction for shield 715 may also be sufficiently dense to avoid and/or minimize buoyancy in liquid 101; i.e., such that shield 715 tends to sink in liquid 101.

In some embodiments, shield 715 may comprise a planar member, with an upper planar surface 716. This upper planar surface may be physical structure that functions as a barrier to prevent touching of element 702 and/or a component of at least one heating element 701. A shape of upper planar surface 716 may be constrained and/or limited by the overall shape of element 702 and/or location(s) of element 702 within interior volume 220. The shape of upper planar surface 716 may be constrained and/or limited by the location(s) of gas-diffuser-tubing(s) 801 within interior volume 220, such that upper planar surface 716 may not block nor obstruct release of gas bubbles from gas-diffuser-tubing(s) 801. In some exemplary embodiments, gas-diffuser-tubing(s) 801 may be concentrated at a middle and/or a center of bottom interior surface 217, and thus in such embodiments, upper planar surface 716 may not be located over such a center and/or over such a middle of bottom interior surface 217. In some embodiments, there may sufficient upper planar surface 716 to substantially cover all elements 702 that may be located in interior volume 220. See e.g., FIG. 7B, where there may be one shield 715 and one continuous upper planar surface 716, but that may be in a “U” shape with two prongs, when viewed from above, such each of the two prongs covers one element 702. See e.g., FIG. 7C and FIG. 7D. In some embodiments, there may sufficient upper planar surface 716 to substantially cover all elements 702 that may be located in interior volume 220, but without covering nor obstructing gas bubbles from gas-diffuser-tubing(s) 801.

In some embodiments, shield 715 may comprise a liquid passage means 717. See e.g., FIG. 7A, FIG. 7B, FIG. 7C, FIG. 7D, and FIG. 7G. Liquid passage means 717 may comprise at least one opening through upper planar surface 716 of shield 715. Liquid 101 may pass through liquid passage means 717 such that liquid 101 may be in removable physical contact with element 702 (or the coating of element 702). In some embodiments, liquid passage means 717 may comprise a plurality of such openings. See e.g., FIG. 7A, FIG. 7B, FIG. 7C, FIG. 7D, and FIG. 7G. In some embodiments, the plurality of such opening may be selected from one or more of: slots (slits), holes, parallel slots, holes in geometric patterns, slots in geometric patterns, linear slots, curved slots, a mesh, combinations thereof, and/or the like. Parallel linear slots may be depicted in the FIG. 7 series of figures for liquid passage means 717. In some embodiments, the slots may run horizontally (or substantially horizontally). In some embodiments, the slots may be run vertically (or substantially vertically).

In some embodiments, element 702 may be located closer to at least one base 215 than to rim 225, such that heating liquid 101 generates convective current flow of liquid 101, with denser (cooler) liquid 101 moving downwards and less dense (warmer) liquid 101 moving upwards within internal volume 220. In some embodiments, such convective flow of liquid 101 may also not be impeded (significantly) by the structural geometry of liquid passage means 717. In some embodiments, such convective flow of liquid 101 may also be facilitated by the structural geometry of liquid passage means 717. In some embodiments, such convective flow of liquid 101 may for vertically oriented eddies of liquid 101 within internal volume 220. Such vertically oriented eddies of liquid 101 may facilitate substantially uniform temperature of liquid 101.

In some embodiments, shield 715 may comprise shield-attachment-means 718. In some embodiments, shield-attachment-means 718 may be how shield 715 may attach to one or more of: the vessel (e.g., vessel 200), the breathing apparatus, and/or the head rest subassembly. In FIG. 7A and FIG. 7B, shield 715 may attach to vessel 200 via shield-attachment-means 718. Shield-attachment-means 718 may comprise structure which may rest upon complimentary and supportive structure 720 of bottom interior surface 217 (or of at least one base 215). Such complimentary and supportive structure 720 of bottom interior surface 217, may be of vessel lining 200 a. See e.g., FIG. 7H. In some embodiments, this complimentary and supportive structure 720 may a top region of bushing hole 708 and/or a top of LED-housing 950, both or either of which may be structure of: bottom interior surface 217, at least one base 215, and/or structure of vessel lining 200 a. See e.g., FIG. 7H. In some embodiments, where shield 715 may have the “U” shape when viewed from above, with the two prongs, at a terminal end of each prong may comprise the structure which may rest upon complimentary and supportive structure 720, wherein this structure may be shield-legs 719. Each such prong may terminate in a shield-leg 719. See e.g., FIG. 7B, FIG. 7E, FIG. 7F, and FIG. 7G. Each such shield-leg 719 may rest upon bottom interior surface 217 and/or element receiving channel 711.

In some embodiments, shield 715 may also comprise shield-back-panel 721. When shield 715 may be installed in interior volume 220, shield-back-panel 721 may cover one or more ports 210 in: at least one wall 201, at least one side wall 205, and/or second side wall 207 of vessel 200. See e.g., FIG. 7H for such one or more ports 210. See e.g., FIG. 7E, FIG. 7F, and FIG. 7G for shield-back-panel 721. In some embodiments, shield-back-panel 721 may be disposed between the two prongs of the “U” shaped shield 715.

In some embodiments, heater 700 may comprise a thermostat 1107 (see e.g., FIG. 11A) for controlling the means to heat liquid 101. Thermostat 1107 may turn on or off the means to heat liquid 101 as a temperature of liquid 101 varies by thermostat 1107 sensing liquid 101 temperature via a temperature sensor 1106 (see e.g., FIG. 11A). Thermostat 1107 may be in electrical communication with the means to heat liquid 101. That is, in some embodiments, thermostat 1107 may comprise a liquid temperature sensing means (e.g., temperature sensor 1106). In some embodiments, thermostat 1107 may be configured to maintain liquid 101 at 110 degrees Fahrenheit or less. In some embodiments, thermostat 1107 may be configured to maintain liquid 101 at 116 degrees Fahrenheit or less. In some embodiments, thermostat 1107 may be configured to heat liquid 101 proximate to the means to heat liquid 101 (e.g. at least one heating element 701) at 116 degrees Fahrenheit or less. Here, proximate may be within 20 inches of the means to heat liquid 101 (e.g. at least one heating element 701). In some embodiments, thermostat 1107 may be preset during manufacturing such that liquid 101 may not be heated to a temperature which may be harmful to user 9000. In some embodiments, heater 700 may be turned on or off by controller 1100 similar to a bubble controller that may control gas bubbles 125 production (release). In some embodiments, the means to heat liquid 101 (e.g. at least one heating element 701) may be turned on or off by thermostat 1107. In some embodiments, all functions of an independent thermostat 1107 may be performed by controller 1100 (see e.g., FIG. 11A and FIG. 11A discussion below), in which case there may no independent thermostat 1107. In some embodiments, the bubble controller may also turn on and off heater 700, and when heater 700 may be on, temperature may then be controlled by thermostat 1107.

In some embodiments, heater 700 may comprise power source 1115. In other embodiments, power source 1115 may be independent of a given face soaking device. Power source 1115 may be configured to supply electrical power to one or more of: the means to heat liquid 101, the thermostat 1107, controller 1100, and/or any other electrical components of a given face soaking device. In some embodiments, power source 1115 may be an electrical cord 1116 removably connected to an electrical outlet at one end, and wherein the remaining end may be electrically coupled to one or more of: the means to heat liquid 101, thermostat 1107, controller 1100, and/or the any other electrical components of the given face soaking device.

In some embodiments, the means to heat liquid 101 may comprise a liquid circulation pump (not depicted). In some embodiments, heater 700 may comprise the liquid circulation pump. Note, this embodiment is not depicted in the figures. In such embodiments, heating of liquid 101 may be provided by the liquid circulation pump motor, i.e., heat may be derived from the heat emanating from operation of the liquid circulation pump motor. In such embodiments, at least one interior wall surface 203 or the interior surface of at least one base 215 may comprise at least one intake vent (port) to provide liquid 101 from interior volume 220 to the liquid circulation pump. In such embodiments, at least one interior wall surface 203 or the interior surface of at least one base 215 may also comprise at least one exit jet (return) where liquid 101 may be expelled from the liquid circulation pump back into interior volume 220.

In some embodiments, the means to heat liquid 101 may comprise a heating portion of heater 700 that may be removably located outside of internal volume 220. In such embodiments, this heating portion may be a block heater, wherein liquid 101 may be fed into a chamber external to internal volume 220, wherein this heating portion may be located within this chamber, and then at least some liquid 101, that has been heated, may be returned to internal volume 220. Such flow of liquid 101 may be by various pumping means, various impeller means, convection means, and/or any other means suitable for moving some of liquid 101 from internal volume 220 to the chamber and back to internal volume 220. This embodiment may not be depicted in the figures.

In some embodiments, the means to heat liquid 101 may be selected from one or more of: at least one heating element 701, the liquid circulation pump, block heater, and/or the like.

In some embodiments, the means to heat liquid 101 may operate by heating a gas (e.g. air, oxygen, nitrogen, carbon dioxide, nitrous oxide, and/or the like) that may be released from the gas diffuser (e.g., gas diffuser 800). Such heated gas may then heat liquid 101.

FIG. 27A may depict an exemplary embodiment of an exploded perspective view of a U-shaped heater embodiment 2700 for various embodiments of face soaking devices. Such a configuration may be depicted schematically in FIG. 28D. In such embodiments, element 702 may be U-shaped and shield 715, which may removably cover element 702, may also be U-shaped. Element 702 and shield 715 may each run along three of four interior perimeter sides the vessel (e.g. not along the back wall). Bottom interior surface 217 of base 215 may comprise element receiving channel 2745, which may also run along three of four interior perimeter sides the vessel (e.g. not along the back wall). Each connection bushing 2736 and 2737 may pass through a back wall, via two bushing holes, 2761 and 2762. Each electrical terminal 706 may be connected to each connection bushing 2736 and 2737, such that the electrical connections to thermostat 1107, to controller 1100, and/or power source 1115 may be made in mechanical compartment 251. FIG. 27C may depict the exemplary embodiment of an assembled perspective view of U-shaped heater embodiment 2700 of FIG. 27A.

FIG. 27B may depict an exemplary embodiment of an exploded perspective view of a U-shaped heater embodiment 2705 for various embodiments of face soaking devices. Such a configuration may be depicted schematically in FIG. 28F. In such embodiments, element 702 may be U-shaped and shield 715, which may removably cover element 702, may also be U-shaped. Element 702 and shield 715 may each run along three of four interior perimeter sides the vessel (e.g. not along a front wall). Interior surface 217 of base 215 may comprise element receiving channel 2745, which may also run along three of four interior perimeter sides the vessel (e.g. not along the front wall). Each connection bushing 2736 and 2737 may pass through base 215, via two bushing holes, 2761 and 2762 (not depicted in FIG. 27B). In U-shaped heater 2705 embodiment, first bushing hole 2761 and second bushing hole 2762 may be located in at least one base 215 or fourth side wall 209.

FIG. 27D may depict an exemplary embodiment of an exploded perspective view of an O-shaped heater embodiment 2710 for various embodiments of face soaking devices. In such embodiments, element 702 may be O-shaped and shield 715, which may removably cover element 702, may also be O-shaped. Such an “O” shape in some embodiments, may approach an oval, square, and/or rectangular shape, as in a wall picture frame shape. Element 702 and shield 715 may each run along four of four interior perimeter sides the vessel. Interior surface 217 of base 215 may comprise element receiving channel 2745, which may also run along four of four interior perimeter sides the vessel. Each connection bushing 2736 and 2737 may pass through the back wall, via two bushing holes, 2761 and 2762. Each electrical terminal 706 may be connected to each connection bushing 2736 and 2737, such that the electrical connections to thermostat 1107, controller 1100, and/or power source 1115 may be made in the mechanical compartment.

In some embodiments, first edge 2751 of shield 715 of O-shaped heater embodiment 2710 may lock in a gas diffuser membrane when shield 715 may be assembled. O-shaped heater embodiment 2710 may comprise a longer overall element 702 than other heater embodiments, yielding a comparatively lower wattage requirement, which in turn may place a lower heat load upon surrounding materials. Such a four sided shield 715 may be stronger than three sided shield 715 and may be less prone to breakage.

FIG. 27E may depict an exemplary embodiment of an exploded perspective view of a back walled heater embodiment 2715 for various embodiments of face soaking devices. Such a configuration may be depicted schematically in FIG. 28A. In such embodiments, element 702 may be linear or I-shaped and shield 715, which may removably cover element 702, may be a planar member. Element 702 and shield 715 may each run along a bottom back wall of the vessel. Because this back wall heater embodiment 2715 may occupy a shorter linear distance than other heater embodiments, e.g., U-shaped heater embodiment 2700, back wall heater embodiment 2715 may be comparatively higher wattage (compared to U-shape or O-shaped elements 702), which may generate greater heat, and thus element 702 in heater embodiment 2715 may be housed in element receiving tray 2748. Element receiving tray 2748 may be configured to keep element 702 from directly contacting base 215, e.g., bottom interior surface 217, and/or from directly contacting interior surface 203. Element receiving tray 2748 may be constructed of a heat resistant thermoplastic, such as chlorinated polyvinyl chloride (CPVC). Interior surface 217 of base 215 may comprise element receiving channel 2745, which may also run along the bottom back wall of the vessel. Element receiving tray 1648 may be configured to fit within element receiving channel 2745. Connection bushing 2735 may pass through a side wall, via bushing hole 2760. (In other similar embodiments, element 702 may have an overall L-shape, such that connection bushing 2735 may pass through the back wall, via bushing hole 2760, see e.g., FIG. 28B.) A pair of electrical terminals 706 may protrude (or be accessible) from single connection bushing 2735. FIG. 27G may depict the exemplary embodiment of an assembled perspective view of back wall heater embodiment 2715 of FIG. 27E.

FIG. 27F may depict an exemplary embodiment of an exploded perspective view of a T-shaped heater embodiment 2720 for various embodiments of face soaking devices. Such a configuration may be depicted schematically in FIG. 28C. In such embodiments, element 702 may be T-shaped and shield 715, which may removably cover element 702, may be a planar member. Element 702 and shield 715 may each run along a bottom back wall of the vessel. Because this T-shaped heater embodiment 2720 may occupy a shorter linear distance than other heater embodiments, e.g. heater embodiment 2700, heater embodiment 2715 may be comparatively higher wattage (compared to U-shape or O-shaped elements 702), which may generate greater heat, and thus element 702 in heater embodiment 2715 may be housed in element receiving tray 2748. Element receiving tray 2748 may be configured to keep element 702 from directly contacting base 215, e.g. interior surface 217, and/or from directly contacting interior surface 203. Element receiving tray 2748 may be constructed of a heat resistant thermoplastic, such as CPVC. Interior surface 217 of base 215 may comprise element receiving channel 2745, which may also run along the bottom back wall of the vessel. Element receiving tray 2748 may be configured to fit within element receiving channel 2745. Connection bushing 2735 may pass through the side wall, via bushing hole 2760. The pair of electrical terminals 706 may terminate from single connection bushing 2735 and the electrical connection to the two electrical terminals 706 may be made within the mechanical compartment. FIG. 27G may depict the exemplary embodiment of an assembled perspective view of T-shaped heater embodiment 2720 of FIG. 27G.

FIG. 27H may depict an exemplary embodiment of an exploded perspective view of a double heater embodiment 2725 for various embodiments face soaking devices. Such a configuration may be depicted schematically in FIG. 28H. FIG. 27I may depict an exemplary embodiment of an assembled perspective view of double heater embodiment 2725 of FIG. 27H. In double heater embodiment 2725 there may be a pair of separate, distinct, and parallel heating element 701 subassemblies. Each heating element 701 subassembly may run in a direction the front wall to the back wall, with each connection bushing 2735 terminating through the back wall in mechanical compartment 251.

In some embodiments, a given heating element 701 subassembly may comprise at least two electrical terminals 706 (either as a pair per a single connection bushing or with one electrical terminal per connection bushing), at least one connection bushing 2735, and at least one element 702. At least one element 702 may be disposed between each electrical terminal 706 and electrically coupled to each electrical terminal 706. The at least two electrical terminals 706 may be located on one side of at least one connection bushing 2735 with at least one element 702 located on an opposing side of at least one connection bushing 2735. The two electrical terminals 706 may be configured to be electrically coupled to power source 1115, controller 1100, and/or thermostat 1107. At least one connection bushing 2735 may be configured to attach to the vessel or an adapter 2775 attached to the vessel. See e.g., FIG. 27D for adapter 2775.

In some embodiments, the heating element 701 subassembly may comprise a flange 2738. See e.g., FIG. 27A. Flange 2738 may separate at least one element 702 from one or two electrical terminals 706.

In some embodiments, the at least one connection bushing 2735 may comprise a single connection bushing 2735. See e.g., FIG. 27E and FIG. 27F. At least one element 702 may comprise an overall shape when an entirety of at least one element 702 may be viewed, such that the overall shape may be selected from the group comprising: a “T” shape (see e.g., FIG. 27F and FIG. 28C), a “L” shape (see e.g., FIG. 28B), an “I” shape, a “J” shape, and the like. In some embodiments, where there may be one single connection bushing 2735, both electrical terminals 706 (positive and negative) may be located on one side of single connection bushing 2735, i.e. on one side of the flange.

In some embodiments, where there may be one single connection bushing 2735, installment of the heating element 701 subassembly may occur from outside internal volume 220 (e.g., from mechanical compartment 251), e.g. by passing at least one element 702 and at least a portion of the one single connection bushing 2735 into a bushing hole 2760 into internal volume 220.

In some embodiments, where there may be one single connection bushing 2735, installment of the heating element 701 subassembly may occur from inside internal volume 220 (e.g., when the overall shape may be “T” shaped), e.g. by passing at least a portion of the one single connection bushing 2735 into a bushing hole 2760 from internal volume 220 side. See e.g., FIG. 27E and FIG. 27F.

In some embodiments, at least one connection bushing 2735 may comprise two distinct connection bushings, a first connection bushing 2736 and a second connection bushing 2737. See e.g., FIG. 27A, FIG. 27B, and FIG. 27D. The at least one element may comprise an overall shape when an entirety of the at least one element may be viewed, such that the overall shape may be selected from the group comprising: a “U” shape (see e.g., FIG. 27A and FIG. 27B; and FIG. 28D, FIG. 28E, and FIG. 28F), an “O” shape (see e.g., FIG. 27D and FIG. 28G), an ovoid shape, a horseshoe shape, and a semicircle shape, and the like. In some embodiments, where there may be two distinct connection bushings (e.g., first connection bushing 2736 and second connection bushing 2737), one electrical terminal 706 (positive or negative) may be located on one side of each distinct connection bushing. In some embodiments, where there may be two distinct connection bushings, installment of the heating element 701 subassembly may occur from inside internal volume 220, e.g. by passing at least a portion of each connection bushing into two distinct bushing holes from internal volume 220 side. See e.g., FIG. 27A, FIG. 27B, and FIG. 27D.

For example, and without limiting the scope of the present invention, heater embodiments 2700 (see e.g., FIG. 27A), 2705 (see e.g., FIG. 27B), and 2710 (see e.g., FIG. 27D) may be LWD; while heater embodiments 2715 (see e.g., FIG. 27E) and 2720 (see e.g., FIG. 27F) may be HWD.

In some embodiments, a given heater embodiment may comprise shield 715. Shield 715 may comprise a first edge 2751 and an opposing second edge 2752. See e.g., FIG. 27A. Shield 715 may be configured to protect user 9000 from physically touching the heating element 701 subassembly, in particular at least one element 702. In some embodiments, shield 715 may be constructed from a heat resistant thermoformed plastic. For example, and without limiting the scope of the present invention, shield may be constructed from CPVC. Shield 715 may comprise a shield longitude which may be parallel with a longitude of the at least one element 702 (e.g. with the overall shape). First edge 2751 of shield 715 may attach to (or contact) bottom interior surface 217 or may attach closer to bottom interior surface 217 than to interior wall surface 203. Such attachment may be removable in some embodiments. Second edge 2752 may attach to (or contact) interior wall surface 203 or closer to interior wall surface 203 than to bottom interior surface 217.

In some embodiments, shield 715 may be a planar elongate member. The planar elongate member may comprise the shield longitude and a shield transverse width 2753. The shield longitude and shield transverse width 2753 may be substantially perpendicular to each other. First edge 2751 and second edge 2752 may be disposed opposite from each other, separated by shield transverse width 2753. See e.g., FIG. 27A.

In some embodiments, shield 715 may comprise liquid passage means 717. See e.g., FIG. 27A. Liquid passage means 717 may comprise at least one opening through opposing major surfaces of shield 715. Liquid 101 may pass through liquid passage means 717 such that liquid 101 may be in removable physical contact with at least one element 702 or the coating of at least one element 702. In some embodiments, liquid passage means 717 may comprise a plurality of holes. See e.g., FIG. 27B. Some such holes may be located into two groups, with a first group located closer to first edge 2751 than to second edge 2752; and with a second group located closer to second edge 2752 than to first edge 2751. In some embodiments, liquid passage means 717 may comprise a plurality of slots (slits). In some embodiments, the plurality of slots may be parallel. See e.g., FIG. 27A. In some embodiments, the plurality of slots may run horizontally. In some embodiments, such horizontal slots may be grouped into two rows of slits, a first row located closer to first edge 1651 than to second edge 1652; and a second row located closer to second edge 1652 than to first edge 1651. In some embodiments, the plurality of slots may be run vertically. See e.g., FIG. 27A.

In some embodiments, at least one element 702 may be located closer to at least one base 215 than to rim 225, such that heating liquid 101 generates convective current flow of liquid 101, with denser (cooler) liquid 101 moving downwards and less dense (warmer) liquid 101 moving upwards within internal volume 220. Such convective flow of liquid 101 may also be facilitated by the structural geometry of liquid passage means 717, such that relatively cooler liquid 101 may enter liquid passage means 717 closer to first edge 2751 to be heated by at least one element 702, and relatively warmer liquid 101 may leave liquid passage means 717 closer to second edge 2752.

In some embodiments, at least one element 702 may be located in a vertical direction (up/down direction) within the vessel (e.g., vessel 200), closer to at least one base 205 than to rim 225 of the vessel. Such vertical positioning of at least one element 702 may facilitate convective flow of liquid 101. In some exemplary embodiments, at least one element 702 may not be physically touching bottom interior surface 217, nor physically touching any interior wall surface 203. That may be done to avoid increased manufacturing costs that may result if at least one element 702 did physically touch bottom interior surface 217 and/or any interior wall surface 203, because then bottom interior surface 217 and/or interior wall surfaces 203 might require construction from materials (e.g., CPVC) capable of withstanding greater heat loads to avoid deformation under heat produced from the at least element 702. Such heat resistant materials of construction may cost more than corresponding materials with less heat resistance.

In some embodiments, element 702 may be located closer to a back wall of vessel 200 than a front wall of the vessel. See e.g., FIG. 27E and FIG. 27F. In some embodiments, a majority of at least one element(s) 702 may be parallel with the back wall, such as when the overall shape may be linear (e.g. “I” shaped), “T” shaped, “J” shaped, and/or “L” shaped. See e.g., FIG. 27E, FIG. 27F, FIG. 28A, FIG. 28B, and FIG. 28C.

In some embodiments, the at least two electrical terminals 706, when assembled, may protrude from a side wall 205 and/or base 215. See e.g., the FIG. 27 series of figures. For example, and without limiting the scope of the present invention, the overall shape may be linear, “I” shaped, “L” shaped, or “J” shaped. In some embodiments, the at least two electrical terminals 706, when assembled, may protrude into mechanical compartment 251.

In some embodiments, the at least two electrical terminals 706 may protrude from the back wall (e.g., second side wall 207 in FIG. 7N). See e.g., FIG. 27E and FIG. 27F. For example, and without limiting the scope of the present invention, the overall shape may be “L” shaped, “I” shaped, linear shaped, “J” shaped, or “T” shaped.

In some embodiments, the front wall (e.g., fourth side wall 209) may be where neck-gasket-accommodator 335 may be located. In some embodiments, the back wall may oppose the front wall. In some embodiments, there may be two side walls (e.g., first side wall 206 and third side wall 208), where each side wall may run from the front wall to the back wall. In some embodiments, the front wall may be fourth side wall 209, the back wall may second side wall 207, and the side wall may be first side wall 206 and/or third side wall 208.

In some embodiments, at least one element 702 may run around an interior perimeter of the at least one base 215, along three of four sides. See e.g., FIG. 27A, FIG. 27B, FIG. 28D, FIG. 28E, and FIG. 28F. For example, and without limiting the scope of the present invention, the overall shape may be “U” shaped, horseshoe shaped, “W” shaped, “M” shaped, as viewed from above. In some embodiments, the at least two electrical terminals 706 may protrude from a back wall, a front wall, a side wall, or base 215 (see e.g., FIG. 27B). In some such embodiments, there may be two distinct connecting bushings, each with one electrical terminal 706, first connection bushing 1636 and second connection bushing 1637. See e.g., FIG. 27A and FIG. 27B.

In some embodiments, at least one element 702 may run around an interior perimeter of at least one base 215, along four of four sides. See e.g., FIG. 27D and FIG. 28G. For example, and without limiting the scope of the present invention, the overall shape may be “O” shaped, circular shaped, or ovoid shaped. In some embodiments, at least two electrical terminals 706 may protrude from a back wall (see e.g., FIG. 27D), a front wall, a side wall, or base 215. In some such embodiments, there may be two distinct connecting bushings, each with one electrical terminal 706, e.g. first connection bushing 1636 and second connection bushing 1637. See e.g., FIG. 27D.

In some embodiments, the heater may comprise two (distinct) heating element 701 subassemblies. See e.g., FIG. 27H. Each heating subassembly may be parallel with each other (when installed into internal volume 220). Each element 702 may run from the back wall towards the front wall. See e.g., FIG. 27H. In some embodiments, a majority of each at least one element may be parallel with side walls (e.g. first side wall 206 and/or third side wall 208). See e.g., FIG. 27H. In some embodiments, each element 702 may be located closer to a side wall 205 than to an other side wall 205, such that each element 702 may be located proximate to each side wall 205 (right and left). In some embodiments, the at least two electrical terminals 706 of each heating element 701 subassembly may protrude from the back wall (see e.g., FIG. 27H), the front wall, either side wall, or base 215. In some embodiments, the at least two electrical terminals 706 of each heating element 701 subassembly may protrude into mechanical compartment 251.

In some embodiments, at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) may be attached to at least one wall 201 (e.g. at least one side wall 205) and/or the at least one base 215. In some embodiments, adapter 2775 may be attached to at least one wall 201 (e.g. at least one side wall 205) and/or at least one base 215. In some exemplary embodiments, at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) may be attached to the back wall or attached to adapter 2775, which in turn may be connected to the back wall, such that the at least two electrical terminals 706 may be accessible from mechanical compartment 251. See e.g., FIG. 27A, FIG. 27D, FIG. 27F, and FIG. 27H.

In some embodiments, the heater may comprise a bushing attachment means. The bushing attachment means may be configured to attach a given heating element 701 subassembly to vessel 200. The bushing attachment means may comprise at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) and at least one bushing hole 2760 (or a first bushing hole 2761 and a second bushing hole 2762). At least one bushing hole 2760 (or a first bushing hole 2761 and a second bushing hole 2762) may pass through at least one wall 201 (see e.g., FIG. 27A, FIG. 27D, and FIG. 27F) or at least one base 215. At least one bushing hole 2760 (or a first bushing hole 2761 and a second bushing hole 2762) may be located in at least one wall 201 or at least one base 215. In some embodiments, at least one bushing hole 2760 may comprise first bushing hole 2761 and second bushing hole 2762, which may be two distinct and separate holes.

In some embodiments, at least one bushing hole 2760 may be sized to receive at least one connection bushing 2735. In some embodiments, at least one bushing hole 2760 may be sized to receive adapter 2775, such as a bulkhead. In some embodiments, at least one bushing hole 2760 may not be threaded. Note in some embodiments, at least one bushing hole 2760 may be functionally equivalent to bushing hole 708. Note in some embodiments, at least one bushing hole 2760 may be structurally equivalent to bushing hole 708.

In some embodiments, first bushing hole 2761 may be sized to receive first connection bushing 2736. In some embodiments, first bushing hole 2761 may be sized to receive adapter 2775, such as a bulkhead. In some embodiments, first bushing hole 2761 may not be threaded. In some embodiments, second bushing hole 2762 may be sized to receive second connection bushing 2737. In some embodiments, second bushing hole 2762 may be sized to receive adapter 2775, such as a bulkhead. In some embodiments, second bushing hole 2762 may not be threaded.

In embodiments wherein at least one bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) may not be threaded (e.g. inside threading or female threading), such embodiments may be exemplary, in that elimination of bushing hole threading may prevent problems of cross threading and/or problems of thread stripping from over tightening, which could necessitate replacement of the entire vessel (e.g. vessel 200). See e.g., FIG. 27F or FIG. 27A.

In some embodiments, at least one bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) may be inside threaded (female threaded) to receive complimentary threading (outside threading) of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737).

In some embodiments, at least one bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) may be inside threaded (female threaded) to receive complimentary threading of exterior outside threading (male threading) of a double threaded adapter. In some embodiment, a sealant, e.g., silicone, may be used in and/or around at least one bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762).

In some embodiments, the bushing attachment means may comprise at least one nut 2770. See e.g., FIG. 27A or FIG. 27F. At least one nut 2770 may comprise inside threading (female threading) to attach to complimentary outside threading of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737). In some embodiments, at least one nut 2770 may be attached to the complimentary threading of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) exteriorly to internal volume 220. Note in some embodiments, at least one nut 2770 may be functionally equivalent to at least one nut 710. Note in some embodiments, at least one nut 2770 may be structurally equivalent to at least one nut 710.

In some embodiments, the bushing attachment means may comprise at least one: gasket 2780, washer 2780, O-ring, and/or the like. At least one gasket 2780, washer 2780, or O-ring may be sized to circumscribe a circumference (e.g., outside diameter) of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737). In some embodiments, at least one gasket 2780, washer 2780, or O-ring may be disposed between at least one nut 2770 and a surface of the at least one wall 201 or a surface of the at least one base 215. In some embodiments, at least one gasket 2780, washer 2780, or O-ring may be disposed between flange 2738 of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) and interior wall surface 203 or bottom intenor surface 217. When secured, flange 2738 may push up against at least one gasket 2780, washer 2780, and/or the O-ring. At least one gasket 2780, washer 2780, or the O-ring may be used to mitigate against liquid 101 leakage, particularly into mechanical compartment 251. Note in some embodiments, gasket 2780, washer 2780, and/or the O-ring may be functionally equivalent to gasket/washer 709. Note in some embodiments, gasket 2780, washer 2780, and/or the O-ring may be structurally equivalent to gasket/washer 709.

In some embodiments, the bushing attachment means further comprise at least one adapter 2775. See e.g., FIG. 27D. In some embodiments, at least one adapter 2775 may comprise a bulkhead and/or the double threaded adapter (i.e., with outside and inside threading). In some embodiments, at least one adapter 1675 may be substantially constructed from a heat resistant thermoformed plastic. For example, and without limiting the scope of the present invention, at least one adapter 2775 may be substantially constructed from CPVC and/or the like.

In some embodiments, bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) may be sized to receive an outside circumference of the bulkhead. The bulkhead may comprises an inside female threaded hole. The inside female threaded hole may be sized to receive complimentary threading of the at least one connection bushing 2735 (first connection bushing 2736 and second connection bushing 2737). In some embodiments, the bulkhead may be permanently attached to bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762). In some embodiments, the bulkhead may be removably attached to bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762). In some embodiments, the bulkhead may be an insert, wherein the vessel (e.g. vessel 200) may be molded around the bulkhead as a mold insert. In some embodiments, the bulkhead may be attached to bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) by a friction fit, ultrasonic welding, heat welding, solvent bonding, and/or chemical adhesive.

In some embodiments, the double threaded adapter (i.e. another type of bushing) may comprise exterior outside threading (male threading) and interior inside threading (female threading). Bushing hole 2760 (or first bushing hole 2761 and second bushing hole 2762) may be inside threaded (female threaded), sized to receive the exterior outside threading (male threading) of the double threaded adapter. The interior inside threading may be sized to receive complimentary threading of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737).

In some exemplary embodiments, adapter 2770 embodiments (e.g. bulkhead or double threaded adapter) may be preferable over a direct connection of at least one connection bushing 2735 (or first connection bushing 2736 and second connection bushing 2737) to the vessel (e.g. vessel 200), because use of adapter 2770 as an intermediary may permit constructing adapter 2770 of a thermoplastic (e.g., CPVC) specifically engineered to take higher heat loads and so a majority of vessel materials need not be engineered to take higher heat loads. Thus, such embodiments would be less expensive to manufacture over an embodiment wherein a majority (or entirety) of the vessel may be constructed of the material able to take higher heat loads.

In some embodiments, any application of threading and complimentary threading for connecting two parts herein, may employ tapered threadings to increase friction and security of such connections. In some embodiments, use of tapered threadings may be used in place of gaskets, washers, and/or O-rings (e.g., gasket 2780, washer 2780, and/or gasket/washer 709).

FIG. 28A through FIG. 28H may depict various element 702 layout configurations, as shown from a top schematic view, depicting various overall shapes of the heater (element 702). These FIG. 28 figures have been noted above in the FIG. 27 series discussion.

FIG. 28A may depict a linear element 702 proximate to the back of the vessel, with element 702 entering the vessel from side wall 205 of the vessel. In some embodiments, elements 702 with an overall shape that may be linear may comprise a single bend, such element 702 loops back on itself, such that there may be one connection bushing with a pair of electrical terminals 706. See e.g., FIG. 7I and FIG. 7J for depictions of such linear elements 702.

FIG. 28B may depict a L-shaped element 702 proximate to the back of the vessel, with element 702 entering the vessel from the back.

FIG. 28C may depict a T-shaped element 702 proximate to the back of the vessel, with element 702 entering the vessel from the back.

FIG. 28D may depict a U-shaped element 702, with element 702 entering the vessel from the back of the vessel.

FIG. 28E may depict a U-shaped element 702, with element 702 entering the vessel from the front of the vessel. For example, FIG. 28E may depict a U-shaped heater embodiment, similar to embodiments 2700 and 2705, except in FIG. 28E, the two connection bushings 2736 and 2737 may extend through the front wall, instead of the back wall or base 215.

FIG. 28F may depict a U-shaped element 702, with element 702 entering the vessel from the bottom of the vessel.

FIG. 28G may depict an approximate O-shaped element 702, with element 702 entering the vessel from the back of the vessel. For example, FIG. 28G may depict an O-shaped heater embodiment, wherein there may be one connection bushing 2735 (with the pair of electrical terminals 706) terminating through the back wall and into the mechanical compartment (not shown).

FIG. 28H may depict a pair of linear element 702, with each proximate to an opposing but parallel side wall 205, with elements 702 entering the vessel from the back of the vessel. FIG. 28H may be representative of the exemplary heater 700 embodiment's element 702 layout configuration as depicted in the FIG. 7 series of figures.

In some embodiments, in addition to various heating equipment (e.g., heater 700 subassembly), there may be various chilling equipment. Or in other embodiments, an alternative to various heating equipment, may be various chilling equipment. In some embodiments, the face soaking devices (e.g., 100) may comprise a chiller for chilling liquid 101 to a temperature below room temperature. In some embodiments, the face soaking devices (e.g., face soaking devices 100) may comprise the chiller for chilling liquid 101 to a temperature above a freezing point of liquid 101. In addition or alternatively, in some embodiments, liquid 101 may be chilled by introduction of ice, such as water ice. Or liquid 101 may be chilled before introduction into interior volume 220.

Chilling liquid 101 by use of a chiller, chilling equipment, and/or by introduction of ice or chilled liquid 101, may then permit various cold therapy to be used to treat face 9010 or other body part(s) which may be removably immersed into the chilled liquid 101. In some embodiments, liquid 101 may be substantially ice. Additionally or alternatively, warm (or hot) therapy may be alternated with cold therapy; wherein such alternation of warmth and cold may aid in increasing blood flow, facilitating removal of cellular toxins (e.g., but not limited to, lactic acid), and/or promoting healing of burned or traumatized tissue.

Now turning to a discussion of the FIG. 8 figures. The FIG. 8 series of figures may comprise FIG. 8A through FIG. 8G. The FIG. 8 series of figures may depict exemplary embodiments of portions of an aerator. In some embodiments, face soaking device 100 may comprise various aerator embodiments. Such aerators may release gas bubbles 125 into liquid 101 within internal volume 220 of vessel 200. In some embodiments, a given aerator embodiment may by a means of supplying a stream of gas to at least one point near a bottom of the interior space of vessel 200, provide for the stream of gas such that there may be a release of bubbles 125 into liquid 101 when the vessel 200 may contain a sufficient quantity of liquid 101. Some portions of aerator embodiments (e.g., a gas diffuser) may be in physical contact with vessel 200. See e.g., FIG. 8A, FIG. 8C, FIG. 8D, and FIG. 8E.

In some embodiments, the aerator may comprise a gas diffuser and a gas source. In some embodiments, the gas source may be coupled to the gas diffuser, such that gas from the gas source may be provided to the gas diffuser. In some embodiments, the gas diffuser may comprise a porous structure. In some embodiments, the gas diffuser may comprise a plurality of pores. In some embodiments, the porous structure may be the plurality of pores. In some embodiments, the gas diffuser may be located within internal volume 220 or positioned, such that gas bubbles 125 from the gas diffuser are released into internal volume 220. The gas source may provide at least some gas to the gas diffuser. In some embodiments, the gas source may be selected from one or more of a cylinder (e.g., a gas cylinder) containing a compressed gas or an air pump for pumping atmospheric air. In some embodiments, the gas diffuser may then release the at least some of the gas through the plurality of pores and/or through the porous structure. When liquid 101 may be occupying some portion of internal volume 220 of vessel 200, the release of the at least some of the gas through the plurality of pores may result in a release of gas bubbles 125 into liquid 101. This may increase an amount of dissolved gas within liquid 101 (as well as non-dissolved gas), including dissolved oxygen, depending upon the composition of the gas.

In some embodiments, the gas diffuser may be located on an interior surface of at least one base 215 (e.g., to a portion of bottom interior surface 217) of vessel 200. See e.g., FIG. 8A, FIG. 8C, FIG. 8D, and FIG. 8E. In some embodiments, the gas diffuser may be located within internal volume 220. In some embodiments, the gas diffuser may comprise one or more gas-diffuser-tubings 801. For example, gas diffuser 800 may comprise one or more gas-diffuser-tubings 801. See e.g., the FIG. 8 series of figures.

In some embodiments, the gas diffuser may be connected to interior wall surface 203 of vessel 200 and below the maximum liquid level. In some embodiments, the gas diffuser, or a portion thereof, may be located on interior wall surface 203 of vessel 200. In some embodiments, the gas diffuser may be removable from interior wall surface 203 of vessel 200.

In some embodiments, the gas diffuser may be integral with interior wall surface 203 of vessel 200. The plurality of pores (and/or the porous structure) may release air (or some other gas) from at least one interior wall surface 203 of vessel 200. The gas diffuser and interior wall surface 203 of vessel 200 may be a single article of manufacture in some embodiments. In such embodiments, at least one wall 201 and the gas diffuser may be injection molded as the single article of manufacture, with airline plumbing needs molded into space between interior wall surface 203 and exterior wall surface 202. For example, between vessel lining 200 a and vessel cover 200 b.

In some embodiments, the gas diffuser may be integral with bottom interior surface 217 of vessel 200. The plurality of pores (and/or the porous structure) may release air (or some other gas) from bottom interior surface 217 of vessel 200. The gas diffuser and bottom interior surface 217 of vessel 200 may be a single article of manufacture in some embodiments. In such embodiments, at least one base 215 and the gas diffuser may be injection molded as the single article of manufacture, with airline plumbing needs molded into space between bottom interior surface 217 and exterior wall surfaces 202. For example, between vessel lining 200 a and vessel cover 200 b. For example, and without limiting the scope of the present invention, see e.g., gas diffuser 800 in FIG. 27A, which may be integral with bottom interior surface 217. Note, a 2D view from a top of gas diffuser 800 in FIG. 27A need not be circular in shape, but could be other 2D geometric shapes, such as, but not limited to: linear runs, with or without curves; ellipses; ovals; regular polygons, with or without rounded corners; irregular polygons, with or without rounded corners; and/or the like.

In some embodiments, the gas diffuser may be gas diffuser 800. See e.g., the FIG. 8 series of figures. FIG. 8A may depict portions of gas diffuser 800 of face soaking device 100, shown from a top view, but with the breathing apparatus (e.g., breathing apparatus 400), the head rest subassembly (e.g., head rest subassembly 500), and shield 715 removed. FIG. 8B may depict portions of gas diffuser 800 exploded from the vessel (e.g., vessel 200), from a top perspective view.

In some embodiments, gas diffuser 800 may comprise one or more gas-diffuser-tubings 801. For example, and without limiting the scope of the present invention, there may be one, two, three, four, five, or six distinct gas-diffuser-tubings 801 in various embodiments. For example, the FIG. 8 series of figures may depict embodiments with three gas-diffuser-tubings 801; and FIG. 29 may depict different layout configurations of one or two gas-diffuser-tubings 801. Additionally, one gas-diffuser-tubing 801 may be looped (and/or bent) onto layout configurations that may be substantially equivalent to two or more gas-diffuser-tubings 801 layout configurations. See e.g., FIG. 29.

In some embodiments, each gas-diffuser-tubing 801 selected from one or more gas-diffuser-tubings 801 may comprise a porous-elongate-member 803 and a central-elongate member 805. In some exemplary embodiments, porous-elongate-member 803 and the central-elongate-member 805 are coaxial with respect to each other. See e.g., FIG. 8E and FIG. 8D. FIG. 8C may depict the portions of gas diffuser 800, shown from a top view, along with a transverse-width sectional line 8D-8D through gas-diffuser-tubings 801. FIG. 8D a transverse-width cross-sectional view along sectional line 8D-8D through gas-diffuser-tubings 801; wherein FIG. 8D may also depict a region of Detail 8E. FIG. 8E may depict a close-up view of Detail 8E showing close up cross-sectional details of gas-diffuser-tubings 801. This cross-sectional close-up of Detail 8E in FIG. 8E may show porous-elongate-member 803 and a central-elongate member 805 and their coaxial relationship to each other.

In some embodiments, central-elongate-member 805 may be located within a cavity of the porous-elongate-member 803. See e.g., FIG. 8E and FIG. 8D. In some embodiments, central-elongate-member 805 may rigid or semi-rigid, permitting bends in the gas-diffuser-tubing 801 to be retained. See e.g., some the various layout configurations of one or more gas-diffuser-tubings 801 shown in FIG. 29. In some embodiments, central-elongate-member 805 may be substantially constructed of a metal. For example, and without limiting the scope of the present invention, in some embodiments, such metals may be selected from: aluminum, copper, steel, and/or the like. In some embodiments, central-elongate-member 805 may be an insulated metal wire, to minimize corrosion to the metal wire and/or to minimize forming an inadvertent battery. Such insulation may be a thermoplastic and/or an elastomer.

In some embodiments, porous-elongate-member 803 may be substantially constructed of a porous material. In some embodiments, this porous material may comprise the plurality of pores of gas diffuser 800. In some embodiments, this porous material may be an elastomeric material. In some embodiments, this porous material may be an open celled foam material.

In some embodiments, each gas-diffuser-tubing 801 selected from one or more gas-diffuser-tubings 801 may comprises two terminal ends, a first end 807 and disposed opposite a second end 809. See e.g., FIG. 8B. Note, in some embodiments, denoting first end 807 from second end 809 may be arbitrary and only for naming convention, in that first end 807 and second end 809 may be structurally equivalent. In some embodiments, first end 807 may be connected to either the gas source or to an intermediary that may be connected to the gas source. In some embodiments, second end 809 may be connected to an end-cap 811, the gas source, or to the intermediary or a different intermediary. The embodiments shown in the FIG. 8 series of figures may show second end 809 connected to end-cap 811. See e.g., FIG. 8F for end-cap 811. In some embodiments, the intermediary may comprise one or more of a connector 813 (or connector 3013) or airline tubing 819. The embodiments shown in the FIG. 8 series of figures may show first end 807 connected to connector 813. See e.g., FIG. 8G for connector 813.

In some embodiments, gas diffuser 800 may comprise one or more end-cap(s) 811. See e.g., FIG. 8B and FIG. 8F. In some embodiments, end-cap 811 may attach to at least one of the terminal ends 807 or 809 of gas-diffuser-tubing 801 to prevent gas escape from that terminal end 807 or 809. See e.g., FIG. 8B and FIG. 8F. FIG. 8F may depict gas-diffuser-tubings 801 removably coupled with end-cap 811, wherein the gas-diffuser-tubings 811 and end-cap 811 may be exploded from a flange-receiver 820 of the vessel (e.g., vessel 200), shown from a partial top perspective view of the interior of the vessel. In some embodiments, end-cap 811 may comprise hose barbs for attachment to at least one of the terminal ends, first end 807 and/or second end 809 of gas-diffuser-tubing 801. In some embodiments, end-cap 811 hose barbs may not be hollow. In some embodiments, end-cap 811 hose barbs may be solid. That is, end-caps 811 may have structure to function as plugs to first end 807 or second end 809 of gas-diffuser-tubing 801. This structure may comprise hose barbs for insertion into an inside diameter of porous-elongate-member 803. In some embodiments, only one terminal end, first end 807 or second end 809, of gas-diffuser-tubing 801 may have end-cap 811 attached thereto; and the remaining terminal end may be connected to airline tubing 819 or to airline tubing 819 through the intermediary. See e.g., FIG. 29 and FIG. 8G. Note, in some embodiments, both terminal ends, first end 807 and second 809 of gas-diffuser-tubing 801 may be connected to airline tubing 819 or both connected to the intermediary. See e.g., FIG. 29 (layout configurations without end-caps 811).

In some embodiments, end-cap 811 may comprise flanges 812, in addition to hose barbs. In some embodiments, end-cap 811 may comprise two opposing flanges 812, wherein the hose barbs may be disposed between both opposing flanges 812. In some embodiments, end-cap 811 may attach to flange-receiver 820. See e.g., FIG. 8F, where flanges 812 may be removably captured by flange-receiver 820. A nature of fit between each flange 812 and each flange-receiver 820 may be a press fit or a frictional fit. Flange-receiver 820 may comprise a pair of oppositely disposed slots sized to receive flanges 812. See e.g., FIG. 8F.

In some embodiments, flange-receiver 820 may be attached to (or integral with): interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217, shield 715, or LED-housing 950. In FIG. 8F, flange-receiver 820 may attach to bottom interior surface 217, proximate to interior wall surface 203. In some embodiments, this proximate distance may be four inches or less.

In some embodiments, gas diffuser 800 may comprise connector 813. See e.g., FIG. 8B and FIG. 8G. Connector 813 may the intermediary. In some embodiments, connector 813 may comprise hollow hose barbs 815 for insertion into the inside diameter of porous-elongate-member 803 of one terminal end, first end 807 and/or second end 809, of gas-diffuser-tubing 801. See e.g., FIG. 8G. FIG. 8G may depict an opposing view from FIG. 8F, wherein FIG. 8G may depict gas-diffuser-tubings 801 exploded from a connector 813 and from an interior back wall of the vessel (e.g., interior wall surface 203 of second side wall 207), shown from a partial top perspective view of the interior of the vessel. As depicted in the FIG. 8 series of figures, it may be first end 807 that may be removably connected to hose barbs 815 of connector 813. See e.g., FIG. 8G. (In some embodiments, connector 3013 may comprise hollow hose barbs 815 for insertion into the inside diameter of porous-elongate-member 803 of one terminal end, first end 807 and/or second end 809, of gas-diffuser-tubing 801. See e.g., FIG. 30A and FIG. 30B.) In some embodiments, the connector (e.g., 813 or 3013) may be for one or more of: connecting at least one of terminal ends, first end 807 and/or second end 809, of gas-diffuser-tubing 801 to a terminal end of airline tubing 819 (see e.g., FIG. 30B); or connecting the least one of the terminal ends, first end 807 and/or second end 809, of gas-diffuser-tubing 801 to the gas source. Thus either connector (e.g., 813 or 3013) may be the intermediary. Note, different sized and/or styled connectors (e.g., 813 and/or 3013) may be used for each of these different connections, e.g., with differences in hose barbs (e.g., 815 or 817). For example, and without limiting the scope of the present invention, hose barbs 815 may be configured for fitting into the inside diameter of porous-elongate-member 803. While hose barbs 817 may be configured for fitting into an inside diameter of airline tubing 819. Both hose barbs (e.g., 815 or 817) may facilitate gas flow within the given hose barb. In some embodiments, other connectors may connect another terminal end of airline tubing 819 to the gas source (not depicted).

Note, in some embodiments, hose barbs 817 may be more broadly characterized as airline tubing connector 817. And in some embodiments, airline tubing connector 817 may comprise hose barbs 817. In some embodiments, airline tubing connector 817 may comprise some portion of threading, such as outside threading for complimentary connection to nut 832 (which may have inside threading). See e.g., FIG. 8G, FIG. 7N, and FIG. 9C for nut 832.

In some embodiments, the connector (e.g., 813 or 3013) may attach to: interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217 of vessel 200, the heat shield 715, or LED-housing 950. In some embodiments, the connector (e.g., 813 or 3013) may attach to bottom interior surface 217 of vessel 200 proximate to interior wall surface 203 of vessel 200 (e.g., the back wall). See e.g., FIG. 8G, FIG. 30A, and FIG. 30B. In some embodiments, this proximate distance may be 2 inches or less. In some embodiments, a nature of this attachment is removable; while in other embodiments, this attachment is permanent. FIG. 8G may show connector 813 for connection to interior wall surface 203 of the back wall at at least one port 210.

Connector 813 may differ from connector 3013 in how the connectors may attach to interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217 of vessel 200, shield 715, or LED-housing 950. Connector 813 may differ from connector 3013 in how at least some of the gas may be delivered (routed) to one or more gas-diffuser-tubings 801 in internal volume 220 from airline tubing 819. Connector 813 may be used in a bulkhead connection manner via at least one port 210 through interior wall surface 203 (e.g., the back wall) into (substantially dry) mechanical compartment 251. In some embodiments, on internal volume 220 side, there may also be a gasket 831 for sealing up against interior wall surface 203 (e.g., the back wall). See e.g., FIG. 8G. Gasket 831 may removably circumscribe a portion of hose barbs 817. In some embodiments, on mechanical compartment side 251, there may be portions of hose barbs 817 (or threading 817) for connection to a terminal end of airline tubing 819. In some embodiments, connector 813 may comprise hose barbs 817 (and/or threading 817) for connection to a terminal end of airline tubing 819. In some embodiments, on mechanical compartment side 251, there may also be a washer and/or a nut 832 to make sure that connector 813 may be secured against interior wall surface 203 without any (or minimal) liquid 101 leakage into mechanical compartment 251. See e.g., FIG. 8G, FIG. 7N, and FIG. 9C.

Whereas, connector 3013 may be used in an “up and over” configuration, where a portion of airline tubing 819 may be brought over rim 225 (or over top opening 226 or over a top slot in rim 225) and down into liquid 101 within internal volume 220, where connector 3013 may reside. See e.g., FIG. 30A and FIG. 30B. FIG. 30A may depict the “up and over” manner of securing one or more gas-diffuser-tubings 801 located within internal volume 220 of vessel 200 to airline tubing 819. A portion of airline tubing 819 may be located outside of internal volume 220. “Up and over” may be with respect to rim 225 of vessel 200. FIG. 30B may depict a close up detailed view of a connection region of FIG. 30A where the one or more gas-diffuser-tubings 801 may be removably coupled to the airline tubing 819 via connector 3013. In some embodiments, airline tubing 819 that may be in internal volume 220 may be fitted into a groove along the back wall of the vessel (e.g., vessel 200). In some embodiments, this groove may be airline tubing channel 3021. In some embodiments, airline tubing channel 3021 may run from bottom interior surface 217 to rim 225 in a substantially vertical manner. See e.g., FIG. 30A.

In some embodiments, connector 3013 may comprise flange(s) 3019 to be captured (e.g., via a snap fit or frictional fit) by some region of: interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217 of vessel 200, shield 715, the LED-housing 950, and/or the like. See e.g., FIG. 30B, where flange(s) 3019 may be removably captured by flange-receiver 3020. In some embodiments, flange-receiver 3020 may be attached to (or integral with): interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217 of vessel 200, shield 715, the LED-housing 950, and/or the like. A nature of fit between flange(s) 3019 and flange-receiver 3020 may be a press fit or a frictional fit. Flange-receiver 3020 may comprise a pair of oppositely disposed slots (i.e., grooves) sized to receive flanges 3019. See e.g., FIG. 30B. In FIG. 30B, flange-receiver 3020 may be attached to (or integral with) bottom interior surface 217, proximate to interior wall surface 203 (e.g., the back wall). In some embodiments, this proximate distance may be four inches or less.

In some embodiments, connector 3013 may comprise hollow hose barbs 815 for insertion into the inside diameter of porous-elongate-member 803 of one terminal end, first end 807 and/or second end 809, of gas-diffuser-tubing 801. See e.g., FIG. 30B. In some embodiments, connector 3013 may comprise hollow hose barbs 817 for insertion into the inside diameter of airline tubing 819 of one terminal end. See e.g., FIG. 30B.

In some embodiments, one or more gas-diffuser-tubings 801 may be located in internal volume 220 of vessel 200. See e.g., FIG. 8A, FIG. 8C, FIG. 8D, and FIG. 8E. In some embodiments, one or more gas-diffuser-tubings 801 may be located in physical contact with or proximate to: interior wall surface 203 of vessel 200, at least one base 215, bottom interior surface 217 of vessel 200, shield 715, and/or LED-housing 950. In some embodiments, portions of one or more gas-diffuser-tubings 801 may be located in physical contact with or proximate to bottom interior surface 217 of vessel 200. For example, and without limiting the scope of the present invention, proximate may be within two inches or less. See e.g., FIG. 8A, FIG. 8C, FIG. 8D, and FIG. 8E.

In some embodiments, at least a portion of one gas-diffuser-tubing 801 selected the one or more gas-diffuser-tubings 801 may be located along a portion of a longitudinal center line of at least one base 215 of the vessel 200. See e.g., FIG. 8A and FIG. 8C. In some embodiments, it may be desirable to locate portions of the one or more gas-diffuser-tubings 801 along this longitudinal center line of at least one base 215, such that gas bubble 125 density may be more likely to be released in locations that are more likely to interact with or benefit face 9010 of user 9000, when face 9010 may be immersed within a portion of liquid 101 in vessel 200.

In some embodiments, one or more gas-diffuser-tubings 801 located in internal volume 220 of vessel 200 may be arranged in a layout configuration with first end 807 of each gas-diffuser-tubing 801 selected from one or more gas-diffuser-tubings 801 may be located closer to the back wall of vessel 200 than to the front wall of the vessel 200. In some embodiments, one or more gas-diffuser-tubings 801 located in internal volume 220 of vessel 200 may be arranged in a layout configuration with second end 809 of each gas-diffuser-tubing 801 selected from one or more gas-diffuser-tubings 801 may be located closer to the front wall of vessel 200 than to the back wall of the vessel 200. See e.g., FIG. 8A and FIG. 8C.

In some embodiments, each gas-diffuser-tubing 801 selected from the one or more gas-diffuser-tubings 801 may proceed in a (substantially) straight linear direction from the back wall towards the front wall. See e.g., FIG. 8A and FIG. 8C.

In some embodiments, each gas-diffuser-tubing 801 selected from the one or more gas-diffuser-tubings 801 may proceed in a straight linear direction from the back wall towards the front wall for a first length and then the gas-diffuser-tubing 801 may proceed with one or more bends; but, where a maximum number of bends may be limited and/or constrained by: surface area of bottom interior surface 217; surface area between LED-housings 950; surface area between at least one side wall 205; and/or surface area between longitudinal arms (prongs) of shield 715. See e.g., FIG. 29.

In some embodiments, some layout configurations of one or more gas-diffuser-tubings 801 when viewed from above may resemble: a letter U, a letter W (with rounded corners), a letter I, a letter L, a number 1, an oval, a circle, a rectangle with rounded corners, other patterns capable of fitting between LED-housings 950, other patterns capable of fitting between at least one side wall 205, other patterns capable of fitting between longitudinal arms (prongs) of shield 715, and/or the like. See e.g., FIG. 29. Patterns which may release and/or direct and/or cause a greater amount or density of gas bubbles 125 to contact the face 9010 of the user 900 may be desirable and exemplary.

In some embodiments, airline tubing 819 may provide an enclosed and non-porous path for a delivery of the at least some of the gas from the gas source to the one or more gas-diffuser-tubings 801. A portion of airline tubing 819 may be depicted in FIG. 30B, otherwise, airline tubing 819 may not be depicted.

In some embodiments, airline tubing 819 may run from the gas source to the one or more gas-diffuser-tubings 801. In some embodiments, airline tubing 819 may run from the gas source to connector 813 or connector 3013; wherein connector 813 or connector 3013 may be connected to one or more gas-diffuser-tubings 801. As noted above, some portion of airline tubing 819 may be routed through a port 210 in a back wall of the vessel 200 (see e.g., FIG. 8G). As noted above, some portion of airline tubing 819 may be routed over rim 225 or over top opening 226 of vessel 200 and into internal volume 220. See e.g., FIG. 30A and FIG. 30B.

In some embodiments, the aerator may also comprise airline tubing 819. Airline tubing 819 may connect the gas source to the gas diffuser (e.g., gas diffuser 800), providing an enclosed path (and non-porous path) for a delivery of the gas or at least some of the gas from the gas source to the gas diffuser. In some embodiments, disposed along a length of airline tubing 819 may be one or more check valves. The check valve may prevent the liquid 101 from traveling within airline tubing 819 towards the gas source.

In some embodiments, the air pump may be replaced with one or more cylinders (gas cylinders) as a supply source for the gas to the gas diffuser (e.g., gas diffuser 800). The gasses within these one or more cylinders may be selected from gasses which may be safe to human skin or safe to terrestrial vertebrate skin. The one or more gas cylinders may be selected from compressed air cylinders, oxygen cylinders, nitrogen cylinders, carbon dioxide cylinders, nitrous oxide, and/or the like. In such embodiments, appropriate pressure regulators may be used in between the cylinders and/or the gas diffuser.

In some embodiments, the air pump may receive atmospheric air and force such air into the gas diffuser (e.g., gas diffuser 800). In some embodiments, the air pump may comprise electrical power cord 1116. Electrical power cord 1116 may receive electrical power from an electrical power source 1115, such as an electrical outlet. The electrical power received by the air pump may provide necessary power to pump (and compress) air with sufficient force to deliver the air to the gas diffuser.

In some embodiments, the air pump may be located outside of internal volume 220. In some embodiments, the air pump may be located inside or partially inside mechanical compartment 251. In some embodiments, the air pump may be located outside of vessel 200. In some embodiments, the gas diffuser may be located in internal volume 220, such that the plurality of pores may release air into internal volume 220.

In some embodiments, the air pump may be housed on exterior wall surface 202. In some embodiments, the air pump may be housed within at least one base 215.

In some embodiments, the air pump may be replaced with compressor 1110 (see e.g., FIG. 11A). In some embodiments, the air pump may be compressor 1110. In such embodiments, compressor 1110 may be configured to supply air to more than one face soaking device 100. One or more compressor(s) 1110 may be used to operate a plurality of face soaking devices 100. When compressor 1110 may be used to supply air to any face soaking device 100, additional plumbing components may also be included, such as manifolds, check valves, valves, filters, oil traps, and/or pressure regulators.

In some embodiments, the aerator may comprise a bubble controller. In some embodiments, the bubble controller may be a pressure regulator and in communication with the gas source or the airline tubing 819. In some embodiments, the bubble controller may be in electrical communication with the air pump or compressor 1110. The bubble controller may control an intensity (density) of bubbles 125 produced from the gas diffuser by controlling an intensity of how hard the air pump or compressor 1110 may work (e.g., as measured by output pressure). The bubble controller may be configured to be engaged by user 9000.

In some embodiments, the bubble controller may be a dial type controller, of either analog or digital design. In such embodiments, user 9000 may rotate the dial to increase or decrease the intensity of produced bubbles. In such embodiments, user 9000 may also turn on or off the air pump.

In some embodiments, the bubble controller may be mounted on one of the exterior wall surfaces 202 of vessel 200. In such embodiments, wiring from the bubble controller to the air pump or compressor 1110 may at least in part be run through and within at least one wall 201 and/or at least one base 215. For example, at least in part between vessel lining 200 a and vessel cover 200 b.

In some embodiments, the bubble controller may be mounted on the air pump or compressor 1110. In some embodiments the bubble controller may be free standing and in electrical communication with the air pump or compressor 1110 via at least one wire disposed between the bubble controller and the air pump or compressor 1110.

In some embodiments, all of the bubble controller's functionality may be performed by controller 1100, wherein there may be no independent bubble controller.

In some embodiments, a given face soaking device (e.g., face soaking device 100) may comprise at least one electromagnetic (EM) emitter 900. See e.g., the FIG. 9 series of figures. In some embodiments, at least one EM emitter 900 may emit EM radiation of a wavelength selected from a range of about 1 picometre (pm) to about 100 megametre (Mm). Note, unless otherwise stated, “about” may mean plus or minus 10% in this context. In some embodiments, at least one EM emitter 900 may emit EM radiation of a wavelength selected from a range of gamma rays to extremely low frequency. In some embodiments, at least one EM emitter 900 may emit EM radiation of a wavelength selected from one or more of the group comprising: gamma rays, hard x-rays, soft x-rays, extreme ultraviolet (UV), near UV, visible light, near infrared (IR), mid IR, far IR, microwave, radio waves, ultra low frequency, super low frequency, extremely low frequency, and/or the like.

Note, at least one EM emitter 900 may not necessarily be a single device capable of emitting across the entire EM spectrum (since different technologies may be required to produce a given range of wavelengths), but rather at least one EM emitter 900 may be a multitude of EM emitting devices wherein each different EM emitting device may be capable of emitting a particular range of wavelengths, such that these different EM emitting devices may collectively as a group be able to cover the entire EM spectrum or a portion thereof.

For example, and without limiting the scope of the present invention, in embodiments wherein treatment of human skin, mammalian skin, and/or terrestrial vertebrate skin may be receive a benefit to such treated skin, wavelengths in the visible light spectrum (about 380 nanometers (nm) to about 770 nm), near UV, UV, and/or near IR may be emitted from at least one EM emitter 900. Treating such skin at such wavelengths may be known as “light therapy” with skin tissue and/or the organism receiving a benefit. However, until this invention, such light therapy was not conducted in combination with simultaneous removable soaking of the skin in liquid 101, and/or in combination with exposures to bubbles 125. Bubbles 125 may enhance the efficacy of such light therapy via optical chain reaction (OCR) as discussed further in the FIG. 12 series of figures discussion below, and/or wherein liquid 101 itself (with additives in some embodiments) may also enhance the efficacy of such light therapy.

In some embodiments, at least one EM emitter 900 may comprise one or more of: a light emitting diode (LED), an incandescent light bulb (including a halogen light source), a fluorescent light source, a high intensity discharge (HID) light source, a mercury lamp, a metal halide lamp, a high pressure sodium (HPS) light source, a laser, a maser, a transducer, a magnetron, a klystron, a traveling-wave tube (TWT), a gyrotron, a field-effect transistor (at least at lower EM frequencies), a tunnel diode, a Gunn diode (transferred electron device (TED)), an IMPATT diode (an impact ionization avalanche transit-time diode), and/or the like.

In some embodiments, at least one EM emitter 900 may be configured to emit light within the visible spectrum (visible to humans). In some embodiments, at least one EM emitter 900 may be configured to emit light within the non-visible spectrum, such as infrared (IR), near infrared, ultraviolet (UV), and the like. In some embodiments, at least one EM emitter 900 may be at least one LED. Various LEDs may be currently available to emit light from the UV spectrum through the visible spectrum and into the IR spectrum. In some embodiments, at least one EM emitter 900 may be at least one incandescent light source and/or at least one fluorescent lamp source.

In some embodiments, at least one EM emitter 900 may be removably attached to one or more of: the vessel (e.g., vessel 200), the breathing apparatus (e.g., breathing apparatus 400), the head rest subassembly (e.g., head rest subassembly 500), the heater subassembly (e.g., shield 715), and/or the gas diffuser (e.g., gas diffuser 800). In some embodiments, at least one EM emitter 900 may be configured to emit electromagnetic radiation (EM) within internal volume 220 such that the emitted EM may irradiate (i.e., shine) upon face 9010 of user 9000 through liquid 101. A portion of at least one EM emitter 900 where the EM may emit from, may be directed towards internal volume 220.

In some embodiments, at least one EM emitter 900 may be a standalone component which may be removable and placed into internal volume 220. In some embodiments, at least one EM emitter 900 may be constructed as component(s) of at least one wall 201 and/or at least one base 215, such that the EM emitted may be directed towards internal volume 220. For example, and without limiting the scope of the present invention, in some embodiments, at least one EM emitter 900 may be constructed as insert(s) where at least one wall 201 and/or at least one base 215 may be molded around such insert(s).

In some embodiments, at least one EM emitter 900 may comprise power source 1115. In some embodiments, at least one EM emitter 900 may receive electrical power from power source 1115, either directly or indirectly via controller 1110. Power source 1115 may be a battery, and in some embodiments at least one battery may be rechargeable. In some embodiments, power source 1115 may be independent from a given face soaking device. In some embodiments, power source 1115 may be wired, such as to an electrical cord 1116 connected to a wall electrical outlet. Such an electrical cord 1116 may pass through at least one port 210 and may be sealed by an electrical cord gasket to prevent leakage of liquid 101.

In some embodiments, such EM emitted from at least one EM emitter 900 may be used for various light therapy treatments of user 9000. Numerous studies have shown significant skin benefits from light therapy. Such skin benefits may comprise: promoting skin tissue repair for faster acne healing; reducing pain associated with skin problems; reducing redness associated with acne; decreasing skin inflammation; reducing pore size and/or minimizing enlarged pores; reducing post acne scarring; promoting a healthier skin tone; promoting a smoother skin complexion, and/or the like. In addition to light therapy having a direct benefit to skin, light therapy may provide indirect benefits, such as the light therapy may be soothing and relaxing to user 9000. Such soothing and relaxing light therapy may then release stress and mitigate against headaches. Release of stress may promote lowering of blood pressure, healing of damaged skin, and a stronger immune system. In some embodiments, various face soaking devices (e.g., face soaking device 100) may be used with or without liquid 101 for light therapy purposes.

In some embodiments, where powerful EM may be emitted from at least one EM emitter 900, various safety mechanisms may be employed to protect user 9000, such as timers and/or filters that may limit EM exposure to user 9000. Powerful EM may include IR, UV, and even visible light of sufficient brightness. Powerful EM may be EM which may harm user 9000 given sufficient exposure time and/or EM with sufficient intensity to be unpleasant to user 9000.

In some embodiments, emitted UV EM from at least one EM emitter 900 may be used for skin tanning purposes, e.g., facial tanning.

In some embodiments, emitted UV EM (or more energetic EM) from at least one EM emitter 900 may be used to sterilize or reduce a microbial load within liquid 101 and/or on the interior (internal) surfaces in internal volume 220 receiving the emitted UV EM (or more energetic EM).

In some embodiments, at least one EM emitter 900 may be shielded and/or insulated from liquid 101, such that liquid 101 may not wet electronics of at least one EM emitter 900. Such shielding and/or insulation may be to mitigate against unintentional short circuiting and/or to mitigate against unintentional electrocution of user 9000. Such embodiments may utilize low voltage and/or a leak detection means. The leak detection means may, upon detecting a leak of liquid 101 into the electronics of any electrical component of the various face soaking device embodiments (e.g., face soaking device 100), terminate electrical flow to such electrical component.

Now turning to at least one EM emitter 900 embodiments depicted in the FIG. 9 series of figures. In some embodiments, at least one EM emitter 900 may comprise at least one LED array 901. The FIG. 9 series of figures may comprise FIG. 9A through FIG. 9C. FIG. 9A may depict a partial view of at least one LED array 901 shown inserted in a given LED-housing 950 of vessel lining 200 a, shown from a top perspective view showing a partial interior view of the vessel (e.g., vessel 200). LED-housing 950 shown in FIG. 9A may be cutaway. FIG. 9B may depict at least one LED array 901 exploded and disposed between vessel lining 200 a and vessel cover 200 b, wherein vessel lining 200 a and vessel cover 200 b may form the vessel (e.g., vessel 200).

In some embodiments, at least one LED array 901 may be comprise two LED array 901. See e.g., FIG. 2G, FIG. 9B, and FIG. 9C. In some embodiments, at least one LED array 901 may be comprise one, two, three, four, five, six, seven, eight, nine, or ten LED arrays 901.

In some embodiments, a given at least one LED array 901 may be an elongate member. In some embodiments this elongate member may comprise at least one LED 902 along a longitude of that elongate member. See e.g., FIG. 9A. In some embodiments, at least one LED 902 may comprise a plurality of LEDs (light emitting diodes) along the longitude of that elongate member. That plurality of LEDs or at least one LED 902 may be configured to outwardly emit EM and/or light (as noted above with respect to at least one EM emitter 900). In some embodiments, the plurality of LEDs or at least one LED 902 may be disposed on only one side of that elongate member, such that EM may be emitted towards face 9010 when face 9010 may be removably within a portion of internal volume 220.

Such embodiments, may comprise one or more of: at least one EM emitter 1244, at least one EM emitter 1245, and/or at least one EM emitter 1247.

Each at least one EM emitter 900 may emit at least some emitted EM 1241 into liquid 101. Each at least one EM emitter may emit at least some emitted EM 1241 into liquid 101. See e.g., FIG. 12A and FIG. 12B.

FIG. 12C may depict a diagram of a phenomenon of an optical chain reaction (OCR) from emitted EM radiation 1241 interacting with at least one bubble 126 from plurality of bubbles 125. FIG. 12D may depict a diagram of the OCR from EM radiation 1241 interacting with plurality of bubbles 125, such as, but not limited to, at least one bubble 126 and another bubble 1228. That is, FIG. 12D may depict how the OCR from one bubble 126 may continue to occur in other bubbles 1228 derived from EM from bubble 126. Bubble 1228 may also be receiving emitted EM 1241 from at least one EM emitter 900 in addition to receiving EM from bubble 126. In some embodiments, OCR interactions may require liquid 101, at least one bubble 126 in liquid 101, and emitted EM radiation 1241 in liquid 101.

In some embodiments, device 1200 and/or the method(s) may comprise an OCR interaction in each bubble 126/1228 that may receive EM radiation (such as emitted EM radiation 1241). A product from the one or more OCR interactions may provide enhanced EM radiation coverage of an exterior of the at least the portion of the article submerged in liquid 101, as compared to if there were no bubbles 125 present in liquid 101. In some embodiments, each OCR may be formed by EM radiation passing through liquid 101 and interacting with at least some of the bubbles from plurality of bubbles 125. EM passing out of such bubbles may further interact with more bubbles. This EM radiation may originally derive from at least one EM emitter 900 (e.g., emitting EM radiation 1241). In some embodiments, such emitted EM 1241 may comprise at least a first beam 1211. In some embodiments, upon first beam 1211 hitting a surface 1227 of at least one bubble 126 from plurality of bubbles 125, first beam 1211 may reflect into a first reflected beam 1212 and may refract into a first refracted beam 1213. In some embodiments, first refracted beam 1213 may continue within at least one bubble 126 until hitting surface 1227 at a different location. In some embodiments, at this different location first refracted beam 1213 may reflect into a second reflected beam 1214 and may refract into a second refracted beam 1215. In some embodiments, second reflected beam 1214 may continue within at least one bubble 126 until hitting surface 1227 at another different location. In some embodiments, second reflected beam 1214 at this another different location may reflect and refract again and continue on this iterative fashion n^(th) times (stated as “n-th” in the claims) producing n^(th) reflected beams 1216 moving interiorly of the at least one bubble 126 and n^(th) refracted beams 1217 moving exteriorly of at least one bubble 126. In some embodiments, first reflected beam 1212, second refracted beam 1215, and/or n^(th) refracted beams 1217 may interact with another bubble 1228 forming another OCR at bubble 1228, and/or may interact with the exterior of the at least the portion of the article, and/or may interact with interior wall surface 203.

In some embodiments, OCR may attenuate, magnify, and/or amplify EM radiation received at the exterior of the at least the portion of the article as compared to EM radiation received at the exterior of the at least the portion of the article if no bubbles 125 were present in liquid 101. In some embodiments, OCR may be occurring in and on more than one bubble 126/1228 resulting in an additive combined attenuation, magnification, and/or amplification of the EM radiation received at the exterior of the at least the portion of the article. For example, and without limiting the scope of the present invention, in embodiments where the emitted EM radiation 1241 may be in the visible light spectrum, this OCR phenomena may be seen visually as the liquid 101 and bubbles 125 appearing to glow, which may manifest in enhanced EM radiation coverage of the exterior of the at least the portion of the article submerged in the liquid, as compared to if there were no bubbles 125 present in liquid 101.

In some embodiments, at each location of interaction of the EM radiation with surface 1227, the EM radiation passing through surface 1227 that may result in the refracted beams, may also result in lensing of those refracted beams. For example, and without limiting the scope of the present invention, EM interactions (e.g. reflections) occurring exteriorly of a given bubble 126/1228 may be convex lensing; whereas, EM radiation interactions (e.g. reflections) occurring interiorly of the given bubble 126/1228 may be concave lensing. For example, EM radiation hitting surface 1227 of the given bubble 126/1228, a portion of such EM radiation may then continue moving interiorly of the given bubble 126/1228 and then exit the given bubble 126/1228 may result in magnification.

Note, OCR occurring on and/or in the one or more bubbles 126/1228 may continue to occur while at least one EM emitter 900 may be emitting EM 1241 into liquid 101 and while plurality of bubbles 125 may be present. Also, note an energy level associated with the EM in a single OCR phenomena may dissipate over time due to EM interactions (reflections and re-fractions) along surface 1227 and because of EM particle (photon) collisions both interiorly and/or exteriorly of any given bubble 126/1228, and/or article EM absorption; however, when there may be at least one EM emitter 900 emitting EM 1241, and plurality of bubbles 125 may be present, the additive (cumulative) of many OCR interactions may be the enhanced EM radiation coverage of the exterior of the at least the portion of the article submerged in liquid 101, as compared to if there were no bubbles 125 present in liquid 101. Additionally, because bubbles 125 are moving in liquid 101, enhanced light therapy provided by OCR tends to provide for very uniform exposure to submerged surfaces of the article being treated. For example, and without limiting the scope of the present invention, this may provide for increased efficacy, greater efficiency, and/or less of a duration of treatment in the case of light therapy as compared to light therapy not using bubbles 125.

In some embodiments, a method for treating the article using bubbles 125 within liquid 101 may comprise the steps:

Step (a): (removably) filling interior volume 220 of vessel 200 with liquid 101 to or below the liquid fill level of interior volume 220;

In some embodiments, this method may further comprise the step of emitting EM radiation 1241 into liquid 101 and irradiating at least some of the exterior of the at least the portion of the article. In some embodiments, this emitted EM radiation 1241 may be from at least one EM emitter 900. In some embodiments, at least some of the bubbles 126/1228 from plurality of bubbles 125 may be disposed between at least one EM emitter 900 emitting emitted EM radiation 1241 and the at least the portion of the article. This may result in enhanced light therapy from OCR.

Step (d): exposing the at least the portion of the article to liquid 101; and

Step (e): exposing the at least some of the exterior of the at least the portion of the article to the emitted EM radiation 1241.

In some embodiments, Step (a), Step (b), and Step (c) in any order precede Step (d) and Step (e). In some embodiments, the exposing of the at least the portion of the article to liquid 101 and the emitted EM radiation 1241 may treat the article.

In some embodiments, this method may further comprise the step of releasing plurality of bubbles 125 into liquid 101. In some embodiments, at least some of bubbles 125 (e.g. 126 and/or 1228) from plurality of bubbles 125 may be disposed between at least one EM emitter 900 and the at least the portion of the article. This may result in enhanced light therapy from OCR.

In some embodiments, a method for treating the article using bubbles 125 and emitted EM radiation 1241 within liquid 101, may comprise the steps of:

Step (a): (removably) filling interior volume 220 of vessel 200 with liquid 101 to or below liquid 101 fill level of interior volume 220;

Step (b): removably receiving at least a portion of the article within interior volume 220 such that the at least the portion of the article may be removably submerged within liquid 101;

In some embodiments, Step (a), Step (b), Step (c), Step (d) in any order precede Step (e), Step (f), and Step (g). (Of course, step (c) occurring before step (a) will first result in releasing bubbles 125 into atmospheric air in interior volume 220, until liquid 101 may be added in step (a).) In some embodiments, the exposing of the at least the portion of the article to liquid 101, plurality of bubbles 125, and to the emitted EM radiation 1241 may treat the article.

In some embodiments, this method (as well as other methods that may comprise the step of emitting EM radiation 1241 into liquid 101 and irradiating the at least some of the exterior of the at least the portion of the article) may further comprise the step of causing at least a portion of the emitted EM radiation 1241 to interact with at least some of bubbles 125 (e.g. 126 and/or 1228) from plurality of bubbles 125 in one or more OCR interactions as depicted in FIG. 12C and FIG. 12D.

In some embodiments, face soaking device 100 may comprise a liquid jet means. The liquid jet means may be configured to direct a stream of liquid 101 at a portion of the face immersed within liquid 101.
